EDIT: I tried putting a 47R in place of the 10R in R3, and the squeal at max gain is gone, though I think it loses just a bit of attack/gets a little sponge-y.
Any other values you guys suggest?
I’d also love to have the Level pot have more range with unity gain being near the middle instead of the first 10% of the throw. Not sure how to make that happen.
I found through more googling that changing the Gain pot to a C1K can make the gain range wider and more usable. If anyone has one I can use to try it I’d appreciate it. Tayda doesn’t have any!
OP: I wired this thing up following their diagram and got a cacophony of noise no matter how the knobs were set, except for Level all the way down. Turning the knobs made some filtering noises too. My guitar signal could still be heard in the noise too, but again, completely unusable. The LED also varied in brightness as I handled the footswitch. I used a 2k2 resistor per the build docs for the LED.
I double checked the wiring diagram with mine. It looked good, but I decided to wire another footswitch in just in case I’d burned up the first one. The LED came on solid but the noise issue persisted.
Triple checked my wiring, jacks etc. Still correct.
So I put another LM386 in the socket. No change.
I re-flowed all my solder joints. No change.
The only difference in my build is that I didn’t use a battery snap, which shouldn’t matter, right?
