Phil of
RuinProjects has decided to share some info on his new 386 and 555 based distortion pedal. The 555 is used to control the gain of the 386 providing for sort of a Tremolo effect on the overall sound. Speed can be adjusted with a single knob. The signal from 555 is isolated through the use of a vactrol assembly. The pedal is powered from a single 9Volt battery. Schematic is included however no guarantees are made that it works as drawn, I looked it over and it looks fine. As a side note the lm386 is pretty loud so it could drive a speaker connected just to the output.
Sound Sample1 ( Drums )
Sound Sample2 (Bass )
(Thanks
Phil)

A similar, and probably more disgusting, effect could be achieved by using the 555 as the 386's Vcc instead of just to control vactrol.
