Yes, it could have been a smaller layout, but to be honest, I'd still be adding some room around the edges for proper mounting points. I also left room for a 1meg resistor on the input, if you are that way inclined.
The schematic can be found here, which is apparently printed on the box. If you don't have the exact values, use the nearest available (4n7 instead of 5n as an example).
note: Volume pot is actually B10k. will update the layout later, 100k will still work fine
ELECTRO-HARMONIX x JHS - BIG MUFF 2 VERO LAYOUT

very glad to see this. I knew as soon as the pedal dropped the diy scene would be on it and
this does not disappoint.
First of all thank you!
I was wondering, would a vintage layout on a big board like the one for the triangle big muff be doable?
Hello - sure, that's workable. I've thought about it before, but never got around to it. I was going to scale it to suit one of the NYC BMP enclosures, as you can get them cheap used.
Hello, I built this yesterday but I'm still having an issue so figured I would ask. I went over all my work, retracing every component multiple times and I can't find anything wrong. While audio probing I accidentally jumped ic pins 1 and 2 on 7/11 and 8/11. This caused this circuit to come to life but it's a pretty gated fuzz. Doesn't sound bad but i know its not right. If I turn it off and on I have to jump those pins to get it to pass signal again. Any idea where I went wrong? Also, in case it matters, the only thing I did differently was using 470pf caps instead of 500pf.
Sorry about that - it's an easy fix, and layout updated. Just need to solder over a couple of cuts (which is blocking pin 1 of each IC to the blue jumper lead)
solder over or jumper the cuts on column 5, row 7 & row 18 more specifically
Thanks so much!! its aliiivvvveeee
Awesome - and how does it sound?
