Great Stuff, Brian.
As I see it, you and Josh fill different niches. Josh is The Biggest Pedal Fan in the Universe, and gets us all charged up with his enthusiasm YES, I need fifty different Screamers in the same box .
You on the other hand are the Bob Ross of electronics, "How about I put a diode here . . what kind of diode? Well . . you can't go wrong with a 4148, so how about we put a pair of happy little 4148s here for some soft clipping . .and maybe a 741 opAmp here . . .it's your pedal . . you can make it however you want..."
hahahaha! 😂
Best comment! 😅😅😅💯
I couldn't have said it better .
There is no wrong or right in here, just happy little accidents.
Put the 1k through the holes, cut off the excess and just >>ha, ha
I love the part when Brian says, “Us do-it-your-selfers.”
Like? Yes.
More? Please.
Do I want my chorus to sound like Whitesnake? Nope, I want it to sound like Alex Lifeson.
Good stuff.
Dimension C. Instant Xanadu.
Michael Cottle Yepp, the chorussy stuff on early Rush is easy enough, Dimension D or C or CE-1 plus a Mistress. „Show of Hands“-era albums are another kettle of fish. Haven‘t really found anything that can adequately mimick a TC 1210, and a „vintage“ 1210 is kinda expensive these days (1400€+ on Reverb).
Thomas Jefferson Erm, nope. Alex‘s rig on the HYF tour at least contained no less than. 6! potential sources of Chorus - GK CPL preamp (built-in), Dimension D, TC 2290, two TC 1210s, and a Yamaha SPX90, all run through mixers. Usage info conflicts between AL himself and his guitar tech at the time, so it‘s difficult to tell for sure now,
In any case, one unit for Chorus/Flanging isn‘t enough to cop his sound. My guess is that he used either the Dim D or one of the TC 1210 in spatial expand / doubler mode as the „baseline“ chorus, and added a 1210 set to a „chorussy flange“ for solos/lead parts, where the modulation thickens noticeably. The Dim D alone doesn‘t do the trick, and neither does a single 1210.
...l‘ve tried...
@Thomas Jefferson Mate, chill, all the albums you name aren't SOH, and yes, a single Dim D is definitely NOT enough for neither AL's live nor studio sound modulation sounds. And yes, there is conficting info from AL himself and his back-then guitar tech from various 80s GW, GFTPM, GP and NME magazine articles on what he used on which track and to which effect.
If it were as simple as "just get a Dimenson C or D", his SOH-era tone wouldn't be anywhere near as difficult to reproduce _closely_ as it is.

UA-cam puts videos like this as the top of my feed, because I watch mostly this type of videos.
Thanks for showing the science/trial-and-error behind the magic. It kinda blows my mind.
Just bought a breadboard to learn more about pedal and amp circuits as a hobby. Definitely interested in this stuff, Brian. Thanks!
What Branda will your pedals be?
Lol good one.
Or “what branda pedals are your fav?!” Lol

LOVE when you do these educational/testing videos on pedals and schematics. Could watch all day!
more of this please! Love this content.
Yes, please, more nerd videos. I also like it when Brian says "DIY'ers like us". Makes me feel cool.
All you need is Fuzz!! Great episode Guru!! Stay safe and healthy!!
As an owner of a Zen Drive - I really thought it was very interesting. Love your videos
This video is fantastic. Id would watch more of this all day.
I would love to see as many of these demonstrations as you’re willing to post. Many thanks
I’m just starting to tool around with pedal building, and without an electric engineering background, I can’t tell you how helpful these videos are. I love all your “techy” videos. Thank you for sharing your knowledge!
This might be my favorite video you've ever made. It would be cool if could further explain why these things work like they do.
Something along the lines of "If you put a resistor and a capacitor in series in this order, you have a low pass filter, and the capacitor sets the cutoff frequency,... now if you put them in that order, you have a high pass filter..."
I don't know what I'm talking about but I sure would like to know.
@k halliday I didn't know about it. Thanks for this wonderful tip !
PLEASE MAKE MORE OF THIS TYPE OF VIDEOS, BRIAN!!??!?!? Me enjoys dem!
Honestly as a sophmore Electrical Engineering student who chose this major to build music equipment for a living, your books and videos have helped me so much in understanding how to creatively build circuits since universities really just focus on the math and graphs of things. Please continue to make videos like this.
That being said i think it would be extremely interesting if you made a vid on some modulation pedals
Thank you for making tutorials/videos like this Brian. I've always struggled with understanding how electronics work.
My favourite part of the day, when mr.Wampler puts out a new video. Would really love to see more of this. Your Enthusiasm for pedalbuilding makes me all juiced up to try and build something. Greetings from Norway :)
I constantly wish I could find in depth geeky circuit talk to help me learn. I'm glad you aren't avoiding it and you can go as deep as you please as far as I am concerned.
Man, couldnt be more excited about this video. As a fellow DIYer, i love these videos and would love to see one on all the popular circuits. These type of videos teach me so much! Thanks for making them
Hi Brian, as a budding DYI'r, I love this type of content. More, please, sir.
I love the video. I'm a guitar player but I'm also an aircraft mechanic (arts & crafts) so I love the lesson in circuits.
No joke this was one of my favorites. Can I put in a request to do the same with the Rat? It’s the Year of the Rat and I’m building a few... Thanks Brian!
Matthew Lees yes!! Bring on the RAT.
Yep, works for me too. A good example of the various distortion families, but also a walk through some other classic pedals like, say, a Phase 90, compressor, octaver, ring modulator, or an analogue delay...
Fuck yeah! Would love to see a video like this of the Rat
Damn yeah, I was just gonna post that myself! The Rat would be great fun, swapping op-amps & transistors and all the tone mods & stuff!
Hell yeah. Finally a Quality quarantine video
2min of testing a Zendrive actually made me buy it, the voice control really made it for me...and watching this now again I think I made the right decision, it´s pretty much perfect as it is...
Few if anyone else does this kind of electronics stuff and I *loved* this one! Thanks Brian! If I may add my favourites to the list, that would be the Blues Driver and the Big Muff. Cheers.
More of this please, it was very interesting!
This kind of "how it works" Videos is great!
Thanks for making it.
Like it. Love it. Need more! This kind of information is exactly what a fair amount of us are looking for.
Loving these drive videos. Thanks for de-mystifying things for many of us. Drives can be the rabbit hole of pedals and can feel like we are chasing our tails most of the times.
I vote "More Circuit DIY analysis". This was very nice to hear the changes as you swapped out components. Very informative. Now something that came to mind was your last comment on the exiting resistor. Can you talk about the standards in signals and what you have to manage coming into the circuit and going out of the circuit? What are the expectations? I figure this is something that needs to be planned and understood to get the entire chain of effects to work properly.
Again, thanks for the video!
fantastic, extremely helpful. I like to look at schematics and try to imagine how the sound changes (specifically frequency response), so it's even more fun to hear the component changes in real time.
I'm still dusting off ancient circuits knowledge from university, so this video format is especially helpful.
Love this content. For the limited amount of quality content about guitar pedal circuit analysis and diy guitar/audio gear, your content is the most enjoyable and easiest to digest. Hope to see more like this in the near future. Thanks
I’ve been building diy pedals for a few years, and really enjoy your videos! It’s like buying a new car. The same type car is everywhere all of a sudden...I think a question or scenario about a guitar pedal, and bam! You have a video up explaining it! Then this morning I sat down and you came on in the same pajamas as I was wearing...I said it’s a sign! I’m gonna build pedals and be like Brian Wampler! LOL 😂 I know, I don’t have a shot...but I’m gonna try it anyway....(if the klon clone is successful;)
Yes please more of this kind of videos for the musician geeks
I love these shows and I have reviewed over 1000 pedals and have taught myself a lot. BUT these shows really make sense of why the cuckoo clock ticks! A big time thanx!!!!
Please do more videos like this one it’s greatly appreciated
I’m a learning bread board DYI guy. Love this kind of video. Thanks Brian.
Yes yes yes yes yes. This is what I have been waiting for! Please do more!
Thanks for this video! I dabble in diy pedal building, and I learn tons from these videos. Please keep them coming.
Great video, Brian! Yes, please do more of these!
Really grateful for you taking the time to do this. I need to get a breadboard!
Sir, I have owned a couple Zendrive’s and own some great gear and your version SMOKES any Zendrive that I have heard.
Nice job ! Great playing ! Yes, more!
Yes please Brian more of this! Maybe let us all DIY our own drive together, i have a breadboard here, and if i know what components to get and how/where/why to place them, we can all make our own drives!
Personally, I dig all of your content. One of my favorite channels for sure.
Cheers
Please do more like these! love this format!
I love this stuff Brian. Between your more technical tutorials, and Josh's broader, less technical history of pedal types, and different pedal companies, I'm constantly entertained. And, I always learn a lot too.
This was great! As a newbie DIY pedal builder, this is exactly the kind of stuff I want to learn. It’s fun to build pedals, but I really want to understand what these circuits are doing. This really helps. Thank you.
Please do more videos like this. I’m trying to play around with tone and want to try my own diy pedals. Thanks!
I love these videos Brian! Keep em coming if you’re so inclined
Very cool, Brian! I'd love to see more videos, like this.
I would LOVE to see more videos like this!
I enjoyed this very much! Great info. I used to be an eletro-mechanical draftsman in another life around 40 years ago at Boeing, but didn't have much of an understanding of what the components and circuits actually did. Music/audio applications makes it fun! You're a good teacher. Thank you.
please please make more of this content!! you are fantastic at explaining!
This is really cool for anyone who has diddled with amp or pedal circuits. Thanks and stay well!
Man I love these. Wish I'd seen these here in Aus during lockdown. I'll be buying your book soon, can't wait!
Great video Brian, of course we want to see more. Thanks,and stay safe!
Mr Wampler, you are amazing. This is a great type of video and very informative. The more you switch different parts in and out, the more the umbrella terms of guitar pedals wash away :)) always fascinating to see and hear what's going on under the hood, than to read about magic diodes, magic op-amps, things that " keep your core tone intact but make it better but without changing it but just adding a little bit of magic but with no alteration to your original signal but just beefing it up but not messing with it but making it more assertive in the mix but without a mid bump....bla bla bla" :)))). Keep it up. Be an educator.
All the best
I have been craving this kind of video for a long time. Thank you, Brian!
Yes! These are the kinds of videos we want. Thanks so much.
Thanks Yes i like the ability to look over your shoulder and watch ya mess with values of components. I have wished i could do this type thing for a long time. Thanks again
Always waiting for this kinda video, please make this stuff more and more.
Yep, this is exactly the sort of article I subscribed for. I'll savour this slowly on my laptop this evening.
Thanks, and stay safe.
Love this, man. Please do more of these for those of us who don't have audio electronics backgrounds but still want to geek out about their pedals.
Thanks for this Brian. I found this a few months after you posted it. Videos like these are very helpful. I’ve recently bought a couple of pedal kits and some breadboards and components. I’ve challenged myself to first breadboard the circuits and get them working before I just solder-by-numbers onto the PCBs so that I can learn what is really going on. I plan to change components in and out from the stock circuit while it’s still on the breadboard to learn more about what each component does. This video was exactly what I’ve been looking for. Been a subscriber to your channel for a while now. I love all your videos. Please, please, please post more videos like these for those of us trying to learn this craft ourselves. Thanks very much. Peace and Rock and Roll!
Great video, would love to see more, and with all types of effects.
Loved it and I'm definitely looking forward to watching more content like this. I wish to see also what's your personal opinion on what's worth changing on a given circuit or not, like if you were to change something on a circuit what would be your first, second and third primary places to look at and why. This type of content is being a grate complement to your "how to modify your 'bd2/ds1' pedal" book. Keep it up.
Brian I definitely want to see more of this type of content. I’m not a circuit builder or tinkerer but learning how my pedals work is very interesting and fun to watch. Thanks for doing what u do
Thank you Brian for all you do! Glad you send me some emails of what is up and I really enjoy these kind of videos! Great playing and I just love the Zen Drive! made my own version crammed inside a 1590bb next to a Timmy circuit. They work well together in fact lol
I just to this video. Yes, please more of these videos!
By the way, THANK YOU for breaking this stuff down, Brian!!
Yeah Brain, more of this please!! Great to see you are doing well... Stay safe!
love this concept, im thinking of getting into pedal circuitry myself and you've been a great help. Thank you Brian!!
Thanks to quarantine I just discovered you, what a great guy you are 👍🏻
Thanks Brian! this kind of videos are so helpful for understand electronics on guitar pedals. Keep On! greetings from Argentina!!
It’s great to have a few clips like this one!
Masterful, now I understand the Zendrive concept well. Thanks a lot
This was great Brian. The concepts are applicable to more than just pedals. Thank you for taking the time to do this.
The video I’ve been waiting for!! Very cool, thank you kind sir!
More of this please! Enjoyed this a lot 😁
These are the best. Helps to really understand how the parts interact with the signal. Thanks
+1 love this kind of video. Thanks for continuing to provide great tools for the DIY people!
LOVE this, would really like to see more dissections of other circuits and how the different components work together to create the final sound.
Brian, thanks so much for making these kinds of videos. As somebody getting into DIY pedal building they're really helpful for learning how these circuits work.
As someone trying to learn more about pedals and start building my own this is exactly what I've been looking for. Love the channel Brian, thank you!!!
Hi Brian,
This is exactly the type of video I asked you to do.
I love it! Thanks
I LOVE this kind of thing. I've been acquiring clones of expensive pedals & changing op amps, caps & resistors. Some have been cool, some not so cool, some produced cool pyrotechnics. 🤘🏼
Yes more please. Would be interesting if you gave your opinions on what the pedal designer was trying to accomplish and how they achieved it. Nice shirt!
Brian, just ordered your book. I love the technical series you’re doing. Been ordering your pedals also. This is one of my favorite channels. I’m always looking for new content from you. Take care.
Thank you!
You should do an online course for the enthusiasts. Most of us just build pedals without knowing whats going on in the circuit. We just follow the map. It would be great!!!!
@ Thanks! I have the Craig Anderton one wich I love but is more like a manual for building specific pedals. I'm going to look for Brians books now :) Thanks
I'd like some p2p tag turret component layout videos with transistors and maybe even ICs done on vero/strip daughter boards so we can learn how to connect off turret strip buffers or drop in power supply daughter boards or something like that. Is there any way we can get a How To Build In Old Skool FX Styles, episode... hour long and get extra nerdy. Not enough super nerdy videos out there! We need a weekly SUPER GEEK hour. thank you so much for all you do Brian. We all greatly appreciate you so much. Be safe man✌🤟🤘🤘🤘
I've never modded a single one of my pedals, but this kind of content is still just so interesting to me. Love the info, the presentation, the general feeling of "yeah, I should do more of that myself" that I'm coming away with. Good stuff.
Thanks so much. I have been playing with this sort of thing myself while in lockdown. But getting it from you is just great. Bring on some more different circuits. Especially modulation.
yes please more of this type of video , I see a turbo distortion sitting on your vox would love to see a video on that one there are a million ds1 and tube screamer mods out there but keep it interesting with some of the not so common pedals
This was amazing. Please do much more of this!
Love this man! Explains the electronics as well as plays. And the jammies with That Pedal Show t-shirt rocks. All you need is Fuzz, Fuzz is all you need. (but we all like reverb, delay, trem, etc too!) I actually bought a hard-copy book, his book on modding pedals. So cool I even did hard-copy (only because I couldn't find it digitally)
Loved it! PLEASE MAKE MORE VIDEOS LIKE THIS!! I’d love your channel to go more in depth into pedal building.
do more. These lessons are awesome. I think you shed the necessary light on the circuits to help everyone make the best choices. I use a Fulldrive 3. You should show if it's overcomplicated against the Zen Drive etc. Have circuit showdown based our your vast knowledge of the electronics. :)
Well done Brian! I'm pretty nerdy lately. Would love to explore pedal mods and building! Thanks for sharing brother! Be Well All!
Absolutely fascinating. Always wondered what all the pieces inside of pedals are for! Thanks.
I love this kind of video. You really have great insight on how pedals work, and what all the different components actually do. You got some great tones out of your breadboard circuit. Thanks
