So I built this, the V4:
Works and sounds AMAZING, except it gets distorted when I hit the lower strings, same with chords. Also, there seems to be a lot of background noise, or is this normal?
I ran out of NE5532's so I used a TL072 instead.
I played around with the 1M resistors and added another 1M in parallel to each of them, no change what so ever. I tried to replace the 78L05 with a L7805 and nothing.
Suggestions?
