From the post
Now verified. But as with DBA Octave Clang I felt it was lacking in gain. But there is a super simple mod to increase the gain of the LM386 amp. Just omit the cut between pin 1 and pin 8. Now we have both a fat fuzz or way over the top octave fuzz with the gain control dimed. Back it of for sitar tones or overdrive.
