yamaha pss6 - circuit bent

i've circuit bent my last toy-keyboard, a yamaha pss-6. i've found an overdrive and a pop effect searching on the IC3 (smaller). the IC2 (bigger) is for totally random noise effects, but too often crashes the toy. i had to replace the speaker with a smaller one to put the two potentiometers for the bends.
