Thank you!
I am having some issues though.
When I first tested it I found myself having to put the gain on my mixer all the way up to hear the sound to desired levels. With no gain it is very very very faint.
Everything is soldered in correctly and using a meter voltage is going through the entire board.
My main worry is:
Might this be a op amp problem? Can using low quality capacitors be a problem as well?
