Same here. Got mine in about 1995 and was the only one of my friends with a Marshall. Everyone thought it was the greatest amp ever because all we had ever heard were Peavey and cheaper fenders. A lot of my style then developed around the Marshall sound, and by 1999 I upgraded to the TSL 100 all tube stack. These valvestates were awesome and gave you serious Marshall feel and power without breaking the bank. I'd really like to get the VSR 265 model with the twin speakers and built in chorus.
@@IgnacioAOlivar I am thinking of getting one of these for around €125, but i live in an apartment. Is it right that i could use the master volume to dial the volume way down but still get the typical tube crunch sound for hard rock but yet on a silent volume?
My first amp, got it in 94 when Grunge was at its peak, still have it although needs servicing.. That thing made so many neighbours unhappy back in the day.. Remember using it once while busking with my mates in a supermarket on a Christmas day ! So, true nostalgia to me... Greetings from France
Bought my 8080 at a pawn shop for about $350 way back in 1995. Still have it, still works, still rocks! I just have to clean the pots every now and again. If you're looking for a 1×12 combo amp that has the volume to play and hang with a drummer, this is a great option!
MusicMan amps had solid state preamps and valve power amps, going back to the mid-70s. They stayed clean up to near full volume. Some had overdrive circuits.
Great video on my fav amps. I collect first and second gen Valvestates. The overdrive 2 on those amps is godly. They are all over 90s death metal records and for good reason. Probably the best amp marshall ever made when it comes to metal besides the JCM 800. There sadly aren't too many demos on YT so i really appreciate your video!!
@@Zbigniew_Piatek Well Death, whether you call them Death Metal or not, I'm pretty sure Chuck just used the amps distortion with just a boost and a bit of studio chorus with a high output dimarzio pickup. At The Gates and In Flames, etc on the early records definitely used the Boss HM-2 with the Valvestate if I'm not mistaken to get that filthy high-gain sound with no care about EQ haha. 😂
I know noel gallagher used one on the first oasis record and subsequent tours with a WEM combo. I had one all thru high achool and was a terrific amp. Wish I never sold it. Have nearly bought one second hand but i habe a kemper too so prob dont need it. Amazing amp tho
Many years , many Marshalls I've had . So glad I have this 90's beloved one again now . I can say that this is one of the best Marshalls I've ever had ..... why ? Because today in 2022 , this is still the perfect amp to own . Small , powerful and full of that up front classic Marshall crushed glass tone , and a super clean channel bonus ! Top of the heap tone and power for either with a band or with its master volume , awesome for studio work . I can take it anywhere and get awesome tone , mic it in the studio , try diff spkrs with it ,etc . This thing works A-1 and never lacks in any respect ..... even after all these years ! Great vid !
Got my Marshall VS265 back today - having been back to the factory for a new valve and a couple of pots. Never let me down since the day I bought it in 1997. Solid (and very loud...). BTW - if you compare the service (£70 all in) to a local amp repair, and throw in a pre-arrange factory tour, museum, studio (with Steve, 35 yrs service) and you can't grumble!!!! Off to the studio for a plugin with my Les Paul....
Interesting video. I've got a 1993 Valvestate 8040 (yes it does have an ECC83) in amongst my amps and its very good as long as you clean up the scratchy pots every so often. You mentioned this being Marshalls first foray into hybrid amps but I believe there's an earlier contender for that title. Back when I was a kid starting to play guitar, I had a second hand 5 watt Marshall Mercury 1x12 combo (model 2060) that had a solid state pre amp and EL84 power amp section. It was only made by Marshall between 1972 & 1973 and originally for sale via mail order catalogues. Pity they didn't opt to stick with 1x12's in their more recent low watt amps !
My ears preferred the 8040 to the 8080, but I bought an 8080 because (I rationalized that) 80 watts had to be better than 40 watts. I think I always regretted it...
Great video, thanks for sharing! I bought one when they first came out. My ears told me that I preferred the 8040, but my brain said I wanted the Clean/Crunch switch on the Clean channel and that 80 watts was better than 40 watts. Mine came with an Eminence speaker rather than a Celestion. I wrote to Marshall asking them why and received a call from Ritchie Fliegler himself (which I thought was pretty cool). He said that they found the Eminence to sound better than any available higher power Celestions at the time. I never really bonded with the amp and sold it years later. Haven't really missed it and have always considered buying an 8040. Probably won't know as they're getting up there in age (as am I) and I have a couple other solid-state amps that I'm enjoying. I believe I read that this was Jim Marshall's favorite amp, simply because they sold so many of them. I think the first available Valvestate amps were the mini-stack, perhaps a 20 watt combo, the 8040, the 8080 and the 8100 head which was paired with the (delightful) 8412 4x12s. I may have considered the stack, but I believe the 8100 was about the same cost as an 8080 combo so even a half stack would have been a lot more expensive.
i just scored a free one of these this morning from some English chap, who couldn't take it back to the UK. Thank you to him, and thanks for great overview of this gem. She is a true beauty.
My first amp was a Peavey Rage 108 that mom got me for Christmas. Couple years later I bought an 8080 and it was awesome! Great memories of that amp. Now I just a great deal on an 8040 and I’m going to get it just for fun!
Sounds relatable! Got mine new since halfway 90’s (playing ‘Kill m all’ all day everyday with the contour setting full to the right…) but I’m using it mostly from effect unit into return socket nowadays. Tomorrow I’ll be picking up a second unit which I’ll be using for an epic stereo adventure :))
I got one from my big brother, it was dirty and so on… I cleaned it up, a bit of contact cleaning and…. Wow. This even brings my flat guitar to a warm tone (but pickups will be changed soon)
This could be a huge plus for non-rock players. With such a great clean channel for funk, neo-soul, surf-guitar....a clean sound is not usually what you'd expect from a Marshall! ...and you have real crunch if you need it.
Thank you, Matt, for this great video and very nice playing!! I bought mine in the summer of 1995. It has been serviced one time and still sounds great. Marshall must have broken the market: thought they sold thousands of this masterpiece. I LOVE MINE. THANK YOU MARSHALL
2 of these are a great option for using as poweramps for ampmodellers/multiefx via the efx returns/line in. So handy to have front access ;-) I've sold a lot of them too, love the price to sound quality ratio. I had a lot of Metal/Thrash customers and they were not hard to sell, to those who couldn't afford the 800s, and some actually preferred the Valvestates i.e. Lasse from Illdisposed.
This is still my main amp even though a JVM410C is standing right next to it. I will renew the pots soon to freshen things up. I love the contour knob. It is so easy to change to different tones with just this one and on top the tone controls work pretty good. Surely ... the JVM shreds the whole house into pieces with power and killer sounds if it wants to, but the 8080 is still my go to amp nonetheless.
I used to plug into a vintage 30 half stack and played many places, including outdoors, and got a bunch of compliments on the tones. Smaller places just use it as the combo, and it ripped! It just quit working, and it's still in the back room somewhere. Think I'll dust it off, send it to the shop..
The amp Jim Marshall was supposed to be most proud of. ! I got mine of eBay for twenty five quid, ten years ago, had crackly pots which when cleaned worked perfectly !
Ive had 2 JCM 800 combos and i now own one of these cause it is a bit easier to move around. I find plenty of good tones on it for blues, Rock and Country. Its got a great reverb. I noticed they also did a JCM 600 which was a full valve amp but cheaper then the 800s and 900s?. They came in a few different models ie a stack a twin speaker combo and i think a single spraker combo?.
Great affordable AMP and great playing! Thank you, I have a Marshall Fifty Split Channel, solid state combo and it rocks! Also a Vr102 combo which is somewhat modern sounding still grat Marshall hybride.
I have a VS102r and it's a fukin bruiser! Best live gigging combo amp, hands down! 100 watt with 2x12 drivers in an easy to carry package. Crazy loud and reliable
I had this (but the stereo chorus version)and the extension cab, purchased from musical exchanges Birmingham back inthe early mid 90,s.its a great amp and today very serviceable!Why did i sell it?I think i was after a fender tone although at the time i did not realise the tone is in your fingers!LOL
How did I miss this one? Love my 8240 stereo chorus valvestate with its right/left effects return. Completely agree with assessment that it's kind of a JC120 with a few more bells and whistles. Don't use my JC120 or AC30 all that much any more.
I can't hear any hum from yours in the video. Mine has a hum as soon as I turn it on, even though no cable is plugged into the input. Is that just filtered by the mic or does this one not have that hum?
My guitar teacher had two valve states in the 90’s and I remember that those amps were highly sensitive for bad grounding. But if the ground connection was good they didn’t hum at all.
Thank you for this video. I took out my Marshall 8080 last week. I love it. I did have bad contacts on the pods. But some wd40 fixed it. Good I see your video. I'm missing my reverb knob and had no idea it was turned on. Hadn't touched the 3 last knobs. So had no clue. Thank you.
I just feel the need ta say : never EVER use oil like the wd40 and such on electric divices. Get contact spray. Ask at any music store , luthier or the likes they will tell you exactly just that.
My bad for not knowing ! Sorry . I have only seen wd40 oil. I shouldve checked it before. My friend worked in a music store where they had people come in all the time saying they sprayed oil into all different electronic places.
I just purchased a used 8080. When you add reverb the amp screams and hums very loudly. Do I need to replace the reverb tank? Where is it located? Thanks in advance..
I very doubt it,firt thing clean the cables going to the tank they are 2 photo connectors, might be bad contacts, then if thats not cured, its something to do with the circuit that drives the reverb. may even be a cracked pot.
It is good to play at low volumes and distortion at home or it's better the 8040? Also, is it (the 8040) loud enough to play with a proper drummer in the room (not for gig) some Death Metal (boosting with a RAT) and having a good time playing? Thanks
Possibly the Chip that drives the reverb tank. Its either an amplifier chip or and Op Amp I cant remember if the leads are ok. or possibly the chip that drives the on off footswitch circuit. I had a head version and a bunch of these ics had all popped.
Hi Matthew, I was drawn to this video and though I'd ask you some questions since you mentioned you serviced this amplifier. I recently plugged a Marshall Valvestate 8040v (made for American market) into 240v UK socket. It is now damaged, don’t ask! … I replaced the fuse and the normal channel made a terrible buzzing noise and the boost channel works but has bad tone and reduced volume. I started at the tube socket (12AX7) to take some readings. Pin 1 (Plate) 248v, Pin2 (Grid) 244v, Pin4/5 (Filament) 18v??, Pin 6 (Plate) 0v, Pin 7 (Grid) 0v. I also have 3.5v AC on plates and grids. D1 and D2 are open. Only one half of the socket is receiving power? Planning to replace the diodes and Zener Diodes. I’d like to get the power supply operating first. I wanted to ask if you know the voltages to expect from the power transformer and auto transformer? I understand the Dagnell T593 is also used in the 8080v model. I hope oyu can help, and thank you for your time.
You can download a service manual of you look the heater wires appear high if to measure the voltage of the pin to ground but the have looped the heaters abs between then I think is about 12v the HT sounds about right. I would look at all of those. Big fat resistors by the transformer And valve and check there all in spec as I have replaced a few in a valve state head I'm currently trying to fix. But sounds like the auto transformer for the valve is ok. Some of those op amps blow for a pastime as they are integral to the overdrive
@@MatthewNorthMusic Hi Matthew, thank you for this insight. I'll check the resistors, I know the 2 x 68 ohm 3W were running hot so I swapped them out for 5W. I'll check the others too. I have downloaded a schematic, but not seen a service manual. I'll check it out tomorrow. Thank you for your reply.
I took the amp apart today to try and cure some random intermittent poping poked around a bit with a chopsticks and found a couple of loose caps fingers crossed that's fixed it
I have an 8240 and it kicks ass. Reverb and chorus almost as good as my 79 JC120. Stereo effects loop return. Weighs nothing. Great amp provided you can fix any noisy pots and being sold for peanuts these days.
This was my first amplifier. I still own it now, after almost 30 years and it still rocks a lot!!!

Great video Matthew!
There is an IC in the preamp stage that is likely to cause trouble and noise and has to be replaced, aside from that it is a good amp.

Hi Matthew, I was drawn to this video and though I'd ask you some questions since you mentioned you serviced this amplifier.
I recently plugged a Marshall Valvestate 8040v (made for American market) into 240v UK socket. It is now damaged, don’t ask! … I replaced the fuse and the normal channel made a terrible buzzing noise and the boost channel works but has bad tone and reduced volume.
I started at the tube socket (12AX7) to take some readings. Pin 1 (Plate) 248v, Pin2 (Grid) 244v, Pin4/5 (Filament) 18v??, Pin 6 (Plate) 0v, Pin 7 (Grid) 0v. I also have 3.5v AC on plates and grids. D1 and D2 are open. Only one half of the socket is receiving power? Planning to replace the diodes and Zener Diodes. I’d like to get the power supply operating first. I wanted to ask if you know the voltages to expect from the power transformer and auto transformer? I understand the Dagnell T593 is also used in the 8080v model.
I hope oyu can help, and thank you for your time.
You can download a service manual of you look the heater wires appear high if to measure the voltage of the pin to ground but the have looped the heaters abs between then I think is about 12v the HT sounds about right. I would look at all of those. Big fat resistors by the transformer And valve and check there all in spec as I have replaced a few in a valve state head I'm currently trying to fix. But sounds like the auto transformer for the valve is ok. Some of those op amps blow for a pastime as they are integral to the overdrive
@@MatthewNorthMusic Hi Matthew, thank you for this insight. I'll check the resistors, I know the 2 x 68 ohm 3W were running hot so I swapped them out for 5W. I'll check the others too. I have downloaded a schematic, but not seen a service manual. I'll check it out tomorrow. Thank you for your reply.
They do run hot but the ones in my head were cracked
I have the Masnall version of this amp
Bought one at a garage flea sale from an old lady which belonged to her dead husband for 50 dollars Au and what a speaker
I picked up one of these today for £40 that just needed de ox on the pots
Fantastic buy. In 10 years you may need to do the pots again but I bet you probably won't need to do much else
I took the amp apart today to try and cure some random intermittent poping poked around a bit with a chopsticks and found a couple of loose caps fingers crossed that's fixed it
Just bought one for 125
what about the 8040? stinks?
I haven't seen one since the early 90s. So Can't really comment. Was a good amp as I recall.
I have an 8240 and it kicks ass. Reverb and chorus almost as good as my 79 JC120. Stereo effects loop return. Weighs nothing. Great amp provided you can fix any noisy pots and being sold for peanuts these days.
The 8240 is far more than a Jazz Chorus
You could get some pretty good Dime tones outta that thing, if you knew how to play. Cheers!
Is this a tube amp?
It had a valve in the overdrive channel pre amp section the rest is solid state
