Hello everyone. Here i am with my first distortion PCB, which works, but has a lot of hum when gain is turned up past 8. Becomes much worse when tone and presence are turned up.
Tone is pregain, presence is post gain.
Weird thing is when i breadboard this its no more noisy than any other high gain pedal - and thats even with it getting power from a different outlet than the rest of my pedalboard.
About the noise - low hum, not like a single coil, just what you’d expect from high gain but much louder. Goes away when turning the guitar down, goes away when playing a buffered guitar. Buffered pedal in front makes no difference.
I am convinced its not an issue with the guitar, as other high gain pedals and also the breadboard do not cause this issue with the same guitar.
I believe something in my layout is not agreeing and for the life of me i can’t figure out what. I’m very new so i know there are lots of mistakes, and i’ve even learned more since i had the boards made. But i wanted some feedback before i waste more money on a bunch of “this MIGHT fix its”.
I want to learn how to do this properly, and repeatably.
I will post pics in next post. Be kind
i know there are some questionable choices on the board, i just don’t know enough to know how to fix them yet lol.
