Hey guys! This might be the wrong place for this, but I figured it got the most traffic on the forum. I'm putting this up on my Perf & PCB blog today and thought I'd share it with you guys too. Anyway, I got an EQD Bellows late last year and traced it. It's fairly simple, but it sound really good (really tho, what EQD box hasn't sounded awesome?). First the guts:
A lot of what's on the board is for the relay bypass switching. Didn't trace that as it would pretty pointless without the code for the PIC, but for the actual effect circuit, here's the schematic:
I breadboarded this and built it on perf using a J201 in place of the PF5102 and it worked well.
Oh, and I whipped up a vero for you guys too:
Enjoy!
