I've gotten a ton of comments about the guitar used in the demo. It's my signature Zio Meteorite. Here are the details: www.zioguitars.com/shop/brad-linzy-the-guitologist-signature-meteorite
Brad has mad guitar skills. I have been watching his vids for years. My favorite part is when he finally gets them repaired and plays.Beautiful playing.
Very enjoyable episode. I have a 1982 2204 CSA Half Stack. Bought it off of an older gentleman in Hearst, Ontario. He played it twice ever ! Just sat in a spare room at his house for 40 years… original tubes obviously. Sounds incredible. So quiet at full volume idle. Dialed in perfectly from the factory 😁
So true that the fuse needs to be checked and never assume the existing fuse is correct. After working on a ‘63? Brown Tolex Fender Super back round 1992, got a call from the owner that instead of the fuse he found a rusty old nail 😮 Glad he checked it for whatever reason he did and afterwards I made it routine to check the fuses
I had two 100w jmp heads for years, loved them. Quit playing for 20 years so they slipped away. Now playing dsl20 and happy for recording, has 2 el43s.
F*** yeah! Good to see an upload Brad! You’re right, the 2204 is THEE amp from Marshall . Love them so much I’ve got 3 of them and each one sounds different . My 77 sounds modded , crazy high gain but if you look at the board, not a single mod.
Agreed....that's a masterpiece of an amp you have there. And, the fact that Marshal had virtually ZERO consistency with parts, or quality, back then, makes a good one even more valuable. There are a few on Reverb I'd consider buying but no sound clips. With the prices they're asking, I don't feel comfortable, knowing that. I envy the guys that have one in good condition, though. Every hot-rodded rock-n-roll amp used that tone as its fundamental tone. Very cool video...thanks for sharing!
Definitely my favorite Marshall. Such a killer sounding amp! I think that’s the same model that Phil X uses that he calls his barbecue grill amp.. He has the grill of a barbecue on it instead of the front wood panel that says Marshall.
I'm huge fan of the JCM800. To me that is the quintessential rock amp. I did buy a Freidman BE Deluxe which is basically the hot rodded modern JMP Plexi.
Woooo!! I have this exact same amp! (well, 100 watt anyway)! Mine's a 79, unmolested except for a replacement power cord. I couldn't agree more, these are the best Marshall ever made. Friends who own Bogners, VHT, Mesa, etc have borrowed my amp for recording. Interestingly, my 100 watter has an output transformer like twice the size of this 50 watter. It's absolutely MASSIVE, with the low end that comes with a larger OT. They'll have to bury me with this amp 😁 Sweet jams at the end too BTW!!
I noticed the amp was signed by Linda. Many years ago I read an interview with Dave Mustaine and Chris Poland from Megadeth and MegaDave said he would open up Marshalls and look for her name as it was sure to be a screamer. Looks like he wasn't full of shit! Love your vids and channel man, I'm from NC and have lived in Seattle for 20 years so it's nice to hear an intelligent southern accent.
That was awesome man! Hate l missed all but the last 10min of the live premier... Hey l got a project goin. It's a 1963 Silvertone 1482 combo. The particle board cab was beyond shot. So I've de-comboed it and just made a nice little head out of it. Any possumability of doing a video on one of those sometime? They're killer sounding little amps!
@@TheGuitologist Man that would be AWESOME if you'd tackle that next! I didn't like that zig-zag, vertical control layout. So l drilled out the panel and layed them out in a straight line. Then l made a thin aluminum cover plate and riveted it to the front to cover all the old holes. Looks great. But l gotta figure out a practical way to print new graphics one the control panel. Without breaking the bank... If you do that one next, I'll be so stoked! I'll give you my first born son. He ain't worth a shit. But you can take him. Please!
I cannot believe I traded my 100 stack for a Les Paul Standard and some ca$h at Sol Betnum's (Anyone remember that HOUSE with its rooms filled with used music equipment?). But I was never able to play the thing anywhere besides my parent's home without the LAPD or US Marshal showing up within 30 minutes. No exaggeration. They once said, "We followed the sound for a mile to find you" I was using it outside, at my high school. Filled my mom's entire VW Squareback! Even had to scoot the driver's seat forward so I could close the back!
@@alecalfaras5936 I should.have the invoice somewhere but I believe it was about 1300 guilders, which equates to 1300/2.20 in todays euros, with inflation correction
Had a 100w marshall 1978 had a fan like this installed was in it when i got it ,had a separate cord for the fan and a master volume on the back of the head
I know I'm not alone in saying your audience WOULD LOVE TO SEE MORE GUITAR PLAYING by you. Any time you play I'm sitting up, paying serious attention. Fantastic player.
Love it! Interestingly, Brad has a lot Ritchie Blackmore's style in his lead playing. Not sure if that's purely coincidental since he's quite young....born in 1977...😄
It amazes me how companies can already have a design, that they KNOW PEOPLE LOVE AND WANT... but someone in corporate HQ says, "No, we don't make those anymore... now we make THEEEEEEESE." It's like JFC, how stupid are these people?
Brad, unfortunately I traded in my Marshall (same one) for a brand new Hiwatt 100 in the late 1980's. Didn't have a side fan though... I was young and naive.... Oops 🔥🎸🔥
Love your vids and playing! Those master vol ones are great too, my fave is a couple years before, a 1987 non madter 50 watt modded with a 2550 mod done horribly by the guy I bought it from, when I got it I almost stripped everything he did and re did the mod, a 1975 50 watt MKII with a early 74 4x12 with all original non reconed greybacks. Old English Mullards make the final tone difference too!
Had one in the 80s when I was 14. Never liked it for months until some guy at music shop just casually popped a new v1 in and whoosh! That's how it should have sounded all along lol! Cant afford one now of course 😢😢
Hey Brad is that a 1977 model? I have a '77 and it has those same green caps they used for a couple of years. Also has the lower voltage power tranny like mine. Very cool video. I biased mine with my oscilloscope last year and just left a tad bit of crossover distortion there as per Lee Jackson. Since the Plate voltage was relatively low I raised my preamp voltages up to around 325vdc at the PI node by lowering the big 10 K dropping resistor to 5K, the sweet spot as per Jason at headfirst. A good place to start on the preamp gain is about 6 or 7 on these although at lower volumes I go a little higher without getting woofy. Rock ON Man!
It is a 77, yes. I've heard of people playing around with the node voltages before. Never felt a need to do that personally, but not saying great results can't be achieved. For some of the sound tests, I was cranking the Master and doing the Gain on about 3 or 4. On other tests, the Gain was nearly cranked with the Master at 7.
I have this exact amp in fawn tolex. I bought it from an older lady who had bought it for her son when he was 18 years old. He passed away about 10 years ago and she sold it to me. It literally looks brand new. He played it at church, believe that, or not. It has the original Marshall 4X12. It is all original including the speakers in the cab. No mods. It is a fire breather. Great to see you on here, brother!
In 1983 I bought one of these in a twin combo form in fawn color tolex(pretty rare). It was a 1977 model also. I paid $400 for it used for at Deitze music house in Lincoln, NE. I rocked it using a Tom Sholz power soak and we played 4 nights a week for 7 years. It never missed a lick, such a great amp it was. My biggest gigs were opening for the band Head East, also got to open for comedian Joe Piscopo, and the biggest was opening for Billy Squier at a outdoor Festival. Anyway I love this amp too. I sold it to my cousin around 1992 and he still has it today! I want it back, but he wont sell it. Nice job with this amp and also your playing on this one was awesome! Thanks Brad and take care!
Did you ever figure out why his amp was sounding like a blown speaker? I had a Mesa Triple Rectifier that would randomly cut out at practice and shows without any warning 😮... Never at home. As randomly as the amp would cut out it would come right back in a minute or two, or even 30 minutes. Tried EVERYTHING, including bringing a backup amp to shows. Turned out it was a bad pickup switch! See, I would only use one guitar for shows and practice, and different guitars aka my "nice ones that I didnt want beer spilled on or dropped" at home. It took months to figure this out.
What a great sounding amp!!! I really like your format, after the repair and learning all about the amp, you do a demo to let us hear it, great playing as well!
I really enjoyed this video! I have two 1979 100-watt JMPs with the 6550s and it is hands down my favorite. I think I fell in love with these heads in my early 20s when it was the first Marshall I was able to buy (used). Mine are both modded with an effects loop and some preamp tweaks so I’ve probably hurt the collectibility, but so be it. You’ll pry my two JMPs from my cold dead hands! I would love to learn how to bias my amp some day.
Got a B-52 AT100 (FREE)!! It runs pretty hot, so I got one of those thermoelectric fans for like $20. Put it on top with a little homemade duct, works great!
I love this video here, Thanks, I really got A Kick of you playing all of the Instruments, Are you Paul McCartney's Relative? LOL, This is what Paul did on his first solo album after the Beatles, Rock on Brother, Cousin Figel
PS bread I do I did miss you a videos I do miss your videos and I miss you too but you're a unique kind of guy and today is the crazy world of craziness craziest to denying of a world small like f*****-up insane crazy fake everything world so I hope to see more of you again Brad welcome back I hope sincerely about the blind bed and guitars
I was kinda surprised to see you playing bass with a pic, when I know you are fairly adept using your fingers on guitar. You and you and you sounded pretty good though! You guys should start a band..
My friend’s dad had one of these. He passed away a few years ago, and I just didn’t have the cash to buy it from his widow. I did help her sell it for her though. We had it gone over by a tech and they said it even still had the stock tubes. I think I got her a good price and the dude that bought it seemed very happy to find an unadulterated JMP.
Dig the red guitar strap. Marshall really makes great sounding amps... personally, I bought a Katana Artist Mk2 head. Bad power avoidance with solid state. Cool bass too.
It sounds killer! He did a great job on that faceplate overlay. Making the controls go to eleven is perfect. I still love your custom made Meteora. Awesome guitar.
My first Marshall I bought was the JMP 100 Watt head in 1981 and a 4 x 12 matching cab. I gigged with it all through the 80s. Incredible amp. I still have the 1/2 stack today, but haven't as much as turned on the head for 30 plus years. It's all original. Wonder what it would cost to get it back to working order?
I always needed to raise half-stacks at least 2 ft from the floor to get the feedback interaction I was using. Most of the time I used the full stack, but the "noise" complaints were perpetual. "A frustrating MESS"
I like the mods this person did to that amp. Had a JMP Super Lead when I young. The only way I could sounds like that was with a Tube Scream, If I did not want to knock a building down.
1 man band? Well I can't blame you for going for it but...... LoL good job bubba love what you're doing, format works, covers all the bases and comedy to boot!! (I'm only serious) I wish I had the talent) all good nice riffs bro. Good tutorial on Xover dist. I've seen/heard a lot of talking say it can be subjective as to exactly where it occurs but the way you suss it out isn't, I'd say. Keep on keeping on. Peace
What's better than 1 Guitologist? ... 3 of course! Way cool! I'd love to hear some octave fuzz and some sweet delay on the next on please....Hope it's on that SS checkered amp you picked up from that guitar convention in Texas or wherever that was with the leaky roof. : )
Re: Scratchy Pots I don’t know if this will make sense or not, but… At times, when I go to clean some scratchy pots with contact cleaner, the knob I’m cleaning loses it’s “tension”. I mean, when you turn a knob, you may or may not FEEL any “friction” in the pot, BUT after spraying contact cleaner in the pot…you can certainly FEEL that ALL FRICTION IS GONE. You might say it feels all “loosely-goosey” and it feels horribly wrong. Especially compared to before. I may be a dumbass and simply spraying too much cleaner into the pot?? I have considered that……😁 THANKS!!
Any similarities to songs living or dead is purely coincidental and a result of the osmosis of vibrations coming from the Universal source of all power.
A FAN?!?!? REALLY? I own a small handfull of epiphone BC30s. I modded the hell out of them to make them as "boutique" (i hate the word) as possible. The clean channel is quite possibly the best i've ever heard. I gave the dirty channel a nice amount of dirt. Only thing i need to do is convert them to fixed bias so i can get rid of the fan that is there to cool down the cathode bias brick. Other than the fan, they are damn near perfect. And here you have a really nice "boutique" piece, and some jackasshole adds a fan? What the WTF?!?!? BTW, love the VJR in the background.
Hey Brad what a nice surprise to see you will back on UA-cam after that the video of the last one I saw before this when you had stated that you were kind of done with the platform you disappeared off my feet so this was a really nice surprise hey at the end there was that one of your new albums gear that today's youth you know today is he was with the boundless attention capacity for sitting still for no my speech-to-text is doing what it does best which is screwing up so I'm going to kind of cut this one short which is really unusual for me since my comments are usually short novellas novels and the epix it's really great to see you back here I hope that I see more of you in my feed breath and again that music was really great and I'm glad to see that you were appealing to the new generation and again they're endless boundless capacity for paying attention sincerely by the blind bedroom
Hey Bob. It’s nice to see you here, as always. I have a second channel called The Fixologist where I work on other random stuff like lawnmowers. I’d been doing a bunch of that stuff lately.
@@TheGuitologist as always thank you so much for your reply Brad I guess I'll have to follow you over at the fixologist I hope that when I first heard fixologist I was hoping or I should say I saw it it might have had to do with junkies or something LOL bad joke what can I say had a lot of experience with lawn mowers back in the day when I had a go-kart and a minibike living in New York City the go-kart was kind of unusual living in New York City having a go-kart but hey you know my parents didn't want to get me a mini bike because it would be too dangerous so I went out and I work at a carwash as a kid back then in the day you could do that and I bought a mini bike frame with everything except the motor on it and I just did a little transplant but anyway I will check you out at that channel because I used to love fixing things everything that had a motor until I went blind I loved music wasn't my only love loved anything with a motor on itloved anything that had a motor on it and I'm repeating myself that might have been repeated to Augusta speech-to-text the screwed up that's my motamouth that won't stop all right Brad I'm going to check out that channel and subscribe again thank you for replying as always Bob the blind bedroom guitar back-in-the-day PSPs back in the day with those small engines in a Briggs & Stratton tecumsah and I graduated the McCullough was a hell of a machine for a go-kart and even admitted by that was a big big thing back then there was a big leap right I'm going to stop for sure one now and Seeley Bob the flybridge
I'll be with the minority for the JMP non-master volume. Up full volume of that old late 60's JMP Super Lead is why my master volume amps gather dust. Preamp cascade goes totally against the idea of pushing an amp. Modern re-active load boxes harness the wall crushing volume. So I respectfully disagree that a 2203 or 2204 top the 1959 or 1987 models.
This looks like the original 2204 amp which doesn’t have the cascaded cold clipper. Marshall originally upped the gain with a 330k plate resistor on V2A which is in large part why it sounds so buzzy.
Seems to me that a lot of the rockers from the 70's seemed to really like the 1959. The problem with that amp is the loudness lol. I'd have to agree that this has the best of the 1959 into JCM 800. At 50 watts it's much more viable for a bedroom to gigging guitarist. I've never seen someone "Lube" a pot before...would you recommend doing that after cleaning?
Sounded damn good Brad. Hey man, you know anything about those bluguitar amp 1 pedal amps?... thomas blug from huges and kettner makes them. All analog pedal, with a russian mini tube in the power section, modeled after marshal amps. Ive heard good things about them just wondered if youve ever had one apart and played thru one?

Mine are both modded with an effects loop and some preamp tweaks so I’ve probably hurt the collectibility, but so be it. You’ll pry my two JMPs from my cold dead hands! I would love to learn how to bias my amp some day.
The biggest regret of my life was selling that head back in the 80s.
Mine was not buying the one that I could have! Did get the checkered board with greenbacks though
Got a B-52 AT100 (FREE)!! It runs pretty hot, so I got one of those thermoelectric fans for like $20. Put it on top with a little homemade duct, works great!
I like hearing you play. The samples at the end really made the video. I know it was to demonstrate the amp, but the samples are good.
Great video and we missed ya! These repair and demo videos are really good for my soul, so I really appreciate them.
About time man. Geesh.🤣😭
I love this video here, Thanks, I really got A Kick of you playing all of the Instruments, Are you Paul McCartney's Relative? LOL, This is what Paul did on his first solo album after the Beatles, Rock on Brother, Cousin Figel
If he only played it in one location, I would consider maybe an RF issue? Where you could have something else getting into it at that location?
PS bread I do I did miss you a videos I do miss your videos and I miss you too but you're a unique kind of guy and today is the crazy world of craziness craziest to denying of a world small like f*****-up insane crazy fake everything world so I hope to see more of you again Brad welcome back I hope sincerely about the blind bed and guitars
I was kinda surprised to see you playing bass with a pic, when I know you are fairly adept using your fingers on guitar. You and you and you sounded pretty good though! You guys should start a band..
Look again. There was no pick. Using my nail.
Oh, ok. I was thinking to see you using your fingers, like I have seen you do on guitar. That's one heck of a nail! @@TheGuitologist
My friend’s dad had one of these. He passed away a few years ago, and I just didn’t have the cash to buy it from his widow. I did help her sell it for her though. We had it gone over by a tech and they said it even still had the stock tubes. I think I got her a good price and the dude that bought it seemed very happy to find an unadulterated JMP.
Dig the red guitar strap. Marshall really makes great sounding amps... personally, I bought a Katana Artist Mk2 head. Bad power avoidance with solid state. Cool bass too.
Always a pleasure to watch a master at work.
Hi. You've said that you very much dislike to work on Mesa amps for various reasons. My question is what's your favorite amp to work on/repair?
Awesome 👏 the jams towards the end of the video gave off Cream vibes. 👍
Dude, you got some tight drum chops. I can play guitar fine, but I'm like a paraplegic monkey on drums.
It sounds killer! He did a great job on that faceplate overlay. Making the controls go to eleven is perfect. I still love your custom made Meteora. Awesome guitar.
I tend to jump in early, but gotta mention. Maybe the speaker was blown? {goin for the obvious}
My first Marshall I bought was the JMP 100 Watt head in 1981 and a 4 x 12 matching cab. I gigged with it all through the 80s. Incredible amp. I still have the 1/2 stack today, but haven't as much as turned on the head for 30 plus years. It's all original. Wonder what it would cost to get it back to working order?
I always needed to raise half-stacks at least 2 ft from the floor to get the feedback interaction I was using. Most of the time I used the full stack, but the "noise" complaints were perpetual. "A frustrating MESS"
That bit with the lead at around 33 minutes was the bee's knees, Daddy-O. Very tasty. (It was all good, but that was especially tasty.)
You're a good dude, Brad. Thanks for being such a great source of information.
I have used Marshalls exclusively since I was a teenager and this is a great sounding Marshall that just needs some tlc. Great video and playing. ✌🏻
I like the mods this person did to that amp. Had a JMP Super Lead when I young. The only way I could sounds like that was with a Tube Scream, If I did not want to knock a building down.
Scratchy Pot?
Smoke it up and play sun Cat Scratch Fever. 😀😀😀
So, nothing really wrong other than dirty pots and sloppy biasing then? Awesome job on a killer amp!
1 man band? Well I can't blame you for going for it but...... LoL good job bubba love what you're doing, format works, covers all the bases and comedy to boot!! (I'm only serious) I wish I had the talent) all good nice riffs bro. Good tutorial on Xover dist. I've seen/heard a lot of talking say it can be subjective as to exactly where it occurs but the way you suss it out isn't, I'd say. Keep on keeping on.
Peace
What's better than 1 Guitologist? ... 3 of course! Way cool! I'd love to hear some octave fuzz and some sweet delay on the next on please....Hope it's on that SS checkered amp you picked up from that guitar convention in Texas or wherever that was with the leaky roof. : )
When is the Guitologist-on-all-tracks self-titled album? You've got some cool stuff going on there dude!
Thanks Wayne. Nice of you to say.
Re: Scratchy Pots
I don’t know if this will make sense or not, but…
At times, when I go to clean some scratchy pots with contact cleaner, the knob I’m cleaning loses it’s “tension”. I mean, when you turn a knob, you may or may not FEEL any “friction” in the pot, BUT after spraying contact cleaner in the pot…you can certainly FEEL that ALL FRICTION IS GONE. You might say it feels all “loosely-goosey” and it feels horribly wrong. Especially compared to before.
I may be a dumbass and simply spraying too much cleaner into the pot?? I have considered that……😁
THANKS!!
Damn, that one song sounded like Band of Gypsys Power of Soul.
Any similarities to songs living or dead is purely coincidental and a result of the osmosis of vibrations coming from the Universal source of all power.
@@TheGuitologist ...across the rainbow bridge.
That's one of MANY I stupidly let go many years back...nice to see ya rockin' the gear again
We hates printed circuit boards, we hates stupid bells and whistles, But hand wired is our precious!!!!
Good to see you back, man.
Also...the three Brad thing was pretty cool.
A FAN?!?!? REALLY? I own a small handfull of epiphone BC30s. I modded the hell out of them to make them as "boutique" (i hate the word) as possible. The clean channel is quite possibly the best i've ever heard. I gave the dirty channel a nice amount of dirt. Only thing i need to do is convert them to fixed bias so i can get rid of the fan that is there to cool down the cathode bias brick. Other than the fan, they are damn near perfect.
And here you have a really nice "boutique" piece, and some jackasshole adds a fan? What the WTF?!?!?
BTW, love the VJR in the background.
Hey Brad what a nice surprise to see you will back on UA-cam after that the video of the last one I saw before this when you had stated that you were kind of done with the platform you disappeared off my feet so this was a really nice surprise hey at the end there was that one of your new albums gear that today's youth you know today is he was with the boundless attention capacity for sitting still for no my speech-to-text is doing what it does best which is screwing up so I'm going to kind of cut this one short which is really unusual for me since my comments are usually short novellas novels and the epix it's really great to see you back here I hope that I see more of you in my feed breath and again that music was really great and I'm glad to see that you were appealing to the new generation and again they're endless boundless capacity for paying attention sincerely by the blind bedroom
Hey Bob. It’s nice to see you here, as always. I have a second channel called The Fixologist where I work on other random stuff like lawnmowers. I’d been doing a bunch of that stuff lately.
@@TheGuitologist as always thank you so much for your reply Brad I guess I'll have to follow you over at the fixologist I hope that when I first heard fixologist I was hoping or I should say I saw it it might have had to do with junkies or something LOL bad joke what can I say had a lot of experience with lawn mowers back in the day when I had a go-kart and a minibike living in New York City the go-kart was kind of unusual living in New York City having a go-kart but hey you know my parents didn't want to get me a mini bike because it would be too dangerous so I went out and I work at a carwash as a kid back then in the day you could do that and I bought a mini bike frame with everything except the motor on it and I just did a little transplant but anyway I will check you out at that channel because I used to love fixing things everything that had a motor until I went blind I loved music wasn't my only love loved anything with a motor on itloved anything that had a motor on it and I'm repeating myself that might have been repeated to Augusta speech-to-text the screwed up that's my motamouth that won't stop all right Brad I'm going to check out that channel and subscribe again thank you for replying as always Bob the blind bedroom guitar back-in-the-day PSPs back in the day with those small engines in a Briggs & Stratton tecumsah and I graduated the McCullough was a hell of a machine for a go-kart and even admitted by that was a big big thing back then there was a big leap right I'm going to stop for sure one now and Seeley Bob the flybridge
Almost understand,Oh no,I have to get an osciloscope,: }
I'll be with the minority for the JMP non-master volume.
Up full volume of that old late 60's JMP Super Lead is why my master volume amps gather dust. Preamp cascade goes totally against the idea of pushing an amp.
Modern re-active load boxes harness the wall crushing volume.
So I respectfully disagree that a 2203 or 2204 top the 1959 or 1987 models.
This looks like the original 2204 amp which doesn’t have the cascaded cold clipper. Marshall originally upped the gain with a 330k plate resistor on V2A which is in large part why it sounds so buzzy.
thanks for the upload Brad and best wishes from Columbus Ohio USA 👍
I have the same amp same year and I always say wind this amp up and hit one chord and it's instant AC/DC....Great video Brad!
Right on!
The Brads! The new top band out of MO!
I have an Ampeg Lee Jackson VL502 that sounds very similar. $250.
JPM 45 wasn't that a Clapton amp at one time
What about the plexi amps, to get that huge Jimi tone?
I actually prefer the Jimi tone thing with these 2203 and 2204 JMP Master Leads. Less prone flubbing out on the bass with humbuckers.
Awesome video Brad . Very informative and entertaining .
Seems to me that a lot of the rockers from the 70's seemed to really like the 1959. The problem with that amp is the loudness lol. I'd have to agree that this has the best of the 1959 into JCM 800. At 50 watts it's much more viable for a bedroom to gigging guitarist. I've never seen someone "Lube" a pot before...would you recommend doing that after cleaning?
Damn son😮
Sounded damn good Brad. Hey man, you know anything about those bluguitar amp 1 pedal amps?... thomas blug from huges and kettner makes them. All analog pedal, with a russian mini tube in the power section, modeled after marshal amps. Ive heard good things about them just wondered if youve ever had one apart and played thru one?
No experience with those.
