That's a Great shout. Thanks, I'll look into it.

Hi all, I’ve been playing with the BB circuits( Bluesbreaker, King of tone, Morning Glory) . I like all of them and have been designing a Perf board with multiple options for each circuit's differences. However I have a few questions as I’ve been playing with the ‘Black Eye’??, mosfet/BS170...

Sorry I ment under the bass pot. Pull it out of the way

I don't want to get ahead of myself here. But i noticed one LED light up on the right side. Can you please take a clear picture underneath the gain pot. Opposite side of the trim pot.

Interesting. I might look into doing something like that. cool idea.!

Solved. I carefully cut away the ground on all 4 corners on both sides, careful not to cut the trace to R14/C9. Had to check a few times with a multimeter. Then I made sure I didn't add to much solder, where it would flow into the ground section. Thanks all for your help.

Fixed! sorta. You guys were on the money. Removed trim R14 and C9. Still continuity to ground, so I Macgyvered it. We have sound and everything seems to be working properly.

I had already removed the trim pot, R14 and C9, inspected and replaced them before I started asking for help. I'll remove them again, do some digging and report back later. Thanks a bunch for all your help.

Continuity to ground here.

I have continuity between ground and R14/C9 and trim (1)

I spent a good time looking and can't see anything out of the ordinary all good . only continuity between 3 and 5 (VDD)

107.1k ohms

9.94k ohms. From memory that was the measurement of R14

Tested good.

Sorry Chuck. I started a new thread.

Hi, I'm having an issue with no audio when engaged. The volume pot and trim pot has a scratchy audio when turned. Led4 lights up when the trim pot is fully counter-clockwise. Led3 lights up when turned 1/4 turn - fully clockwise. I have audio up to IC2 pin 2 and 7 then nothing after that. R14...

Continuity all checks out great. IC2 readings looks odd?

Hi, I'm having the same issue. No audio when engaged. Led4 lights up when the trim pot is fully counter-clockwise. Led3 lights up when turned 1/4 turn - fully clockwise. Audio up to IC2 pin 2 and 7 then nothing after that. R14 tested great but no audio on the left side of it. No audio at C9...

18 volts. This is a grey area for me. I'd like to understand it a little better. I understand not to run pedals at 18 volts if you use 16v caps. If I only use 35v-50v, can I run these pedals at 18 volts? If it has a charge pump, that's a no, no right? If its some sort of fuzz pedal were...
