Oh hai
Nice to see that you clicked on this beautiful PCB.
What will it do you might ask.
Well let me tell you.
A whole fuckton of fuzzy distortion.
And even a hint of octave up.
And If it might interest you you can use this PCB to build a clone of the Fuzzhugger Phantom octave.
You are very welcome
You can also get this as a kit from Musiking here
