I've been fiddling with this circuit off and on for over a year. I built the topographer pre (sounds great together) a while back so it felt necessary to try the percolator with it. I socketed both transistors and the diodes so there was much swapping. Having started mostly with parts I had on hand, it felt really boring of me when I recently bought the legitimate bits and I much preferred the stock percolator. It has stayed this way for over a month and I've been playing with it quite a bit so I figured I should box it up.

I don't have much use for it on bass but man do I enjoy it with my tele. There's nothing over the top about it but the pokey nature of the distortion and the interaction with the volume pot are fantastic. I have a Charlie Christian neck pickup which is at times too fat and warm sounding but backing off the instrument volume really brings the treble back without fully cleaning up like a FF. I actually tried putting this in parallel with a FF type circuit for a minute. Turning the volume down gave both the clean up along with those sparkly highs. It was pretty interesting and I almost housed it that way but ended up choosing simplicity instead.

The Percolator plays well with others. You mentioned the Fuzz Face, and I’ll second that.
I’ve been rockin’ a Fuzz Foundry before the Carcass (which is a Percolator variant I believe) and they get along great.
Great report.
 
@Mentaltossflycoon what did ya end up with for your transistors/diodes? That enclosure is gorgeous 🤩

The HP is hands down my favorite circuit I've built to date. Still need to breadboard/vero Jimi Pink's Juergulator. I actually run my HP dials pretty low, I really dig the low gain stuff from the HP and I still get some amazing harmonics. Works so well as dirt rhythm and kicked up with a boost for a dirty overdrive.

I used a 2n404a, 2n3565, and a few 1n695. I think all from small bear
