Another tip from the author :

Nice site by the way. Another 303 tip - if you've done the external input mod, try feeding the signal from the headphone back into the input for extended bass response (and self oscillation effects - sounds like birds singing), and for more fun and adventure, put some effects pedals like phasors and distortion boxes between the headphone out and the external in for some strange effects when using the 303.
