Right, here's one for all you electronic guru's.
I had an idea for a pedal that basically is like a killswitch but automated. Therefore it would have one switch to kill the signal, however I want another switch that when pressed will kill the signal and then let it back through really quickly, many times, kind of like a tremolo but actually killing the signal every time. This would allow the user to do those staccato sounds with general ease. I also wanted a pot that could control how fast or slowly the signal is killed, example being in a low position the signal is killed once a second and in the highest position about thirty times a second.
I thought I could do this with a 555 astable circuit running into a transistor which then kills the signal when no power is going through it and lets the signal through when power is going through it.
I can't work out a way to get this to work though so I though I'd give you lot a try.
