I took a busted old tube screamer and rehoused it in this cigar box. I added a few pots and a photo-theremin. Now it produces a variety of distortin’, ring modulatin’, filterin’, tone-oscillatin’, and sound crunchin’. It also acts as a rich, squealing stand alone synth box. The photo theremin controls the pitch depending on the brightness of the light.
Here it is running over an SK-1:
And here it is emitting sound on its own (with some Fab Echo D-Lay and a little SK-1 background):

Very nice! Any chance of dropping some hints as to where you bent the circuit to accept your additional pots? Would love to experiment with this as well as I also have a tube screamer begging to be modded into a screamin’ banshee like yours.

Thanks a lot, Eric!
This one was really just a lick and touch voyage of discovery.
Most of the points were on the main chip (I think there was only one). And very easy to find. The hard part was stopping.
Maybe I’ll try to get some photos of the board up here, though.
