Positive Feedbacker

Built for Hanno Leichtmann

This is a tube distortion box with the wild feature of positive feedback-- yes it does make you feel good! Controlled with a switch and a knob this feature allows the sound to be thickened or creates an oscillator at extreme settings whose frequency can be played with the knob. Another example of reusing old parts.
No external power supply is needed everything is built in-- compact and powerful!
