That make sense- thanks for clearing that up-

What is the deal with these transistors? Do they come with leads like this? Or are the leads soldered on AMS the cap covered for aesthetics?

You had, thank you!

Is it possible to run NPN transistors in this? any way and or need to bypass the charge pump? Thanks! Jeff

Good idea

Went through it again- checked out the trimmer and it looked like it had bent a little and maybe was contacting where it shouldn’t- replaced it. Tested all pots, all normal. Sound is better, but still getting the feedback oscillation. I CAN make it go away when I turn back the “tight” knob, I’d...

Hooked it up with no input- footswitch off. High pitch hum still there. I replaced the footswitch and rewired the connections to the board/jacks. No change. Looked under magnification but nothing looks obvious

Trim pot lowers it, but it won’t remove it. Did some more troubleshooting- I can hear it when the pedal is off; very low, but I can hear it in the dry signal. And even in the dry signal with no power to the pedal, the gain and tight knobs change the pitch of the oscillation. I’m thinking it’s a...

I believe so

Just finished this build and it’s acting funny... It’s making a feedback/oscillation. More accurately an oscillation that sounds like feedback- when I adjust the gain, tight, and trimmer, they affect the pitch and intensity of the oscillation. Any ideas? Posting pics Thanks for the help-

Thank you guys very very very much! Great info.

I’m working on a bumble buzz and don’t ha e any 1k8’s... can someone give me an idea of what these are affecting in this circuit? I’d like to understand so I can experiment, or wait for the tayda order lol. Got lots of 1k5’s and 2k2’s

Thank you- I looked at the schematic, and it looked ok to swap, but I appreciate the expert advice. Added a bunch of 4007 to my Tayda cart... pretty darn cheap lol

Realized I don’t have any 4007’s. got lots of 4001’s, 5817’s and 5817’s. Any of these make a good replacement?

Thank you! I’ll check it out
