I'll post pics later... just finally got this together last night and played it in practice. Had a disastrous first build that I just couldn't fix and was likely due to burnt out jfts. Did a 2nd try and the build couldn't have been easier and it fired up first try.
I like jft based drives and have tried a few on bass: pedal pcb modified son of ben and a ss/bs mini. The Chop Shop is my favorite so far. I have enough eq in my line (onboard bass preamp, di/eq last in chain), so not having a tone/eq is just fine with me on this one. I prefer it. I was able to get a good tubey edge of breakup tone that sounded great. Def want to mess with the biasing. I biased at 6V, but want to do it by ear to see if something closer to 4.5V works. Also, I was able to get a nicer breakup at 9V than 18V, but I'll have to mess around with that as well.
