For a while I used the SoundSculpture AB Cadabra ( http://soundsculpture.com/products/pt_abcadabra.htm ) to do something similar controlled from a MIDI footpedal. The midi pedal handled the momentary aspect. The AB Cadabra had excelllent response - fast and quiet.
But I found that I couldn't get the speed from my foot that I wanted, so I had one of my tone pots customized to cut the guitar's output when depressed - it bounces back automatically if I don't hold it down.

Ok, so I have been hinting at building a pedal for a while now, for reasons that I won't go into, my Ego kind of wanted to keep the design some sort of secret,however this has led to nowhere for me so it is time to REVEAL ALL!!!
Basically I want to make a foot operated device that allows a signal to pass only when the button is pressed. Kind of a Poor-Mans-Morse-Glitch Pedal.
I envisaged building it as follows.
two buttons button one simply being on / off
In off position the signal is bypassed directly to the output jack
in the On position it passes to the next momentary button.
Button Two is the activation button,
it is a push to make type switch so initially the signal is dead, however, when the button is pressed the sound is allowed to pass to the output.
I can therefore strum a chord while it is off then tap the button rythmically to let small stabs of sound through.
I came up with this when playing through a broken amp that you had to hold the jack in place in the input, i found that tapping the jack let me do dda-da-da type noises.
anyways basically I know NOTHING about how to do this, I did what seemed reasonable to me but all I got was nasty hiss and buzzing. I would appreciate ANY help or comments on how I may impliment this pedal.
I had once dreamed about making money off this idea, however, it will never be built if I cant get some advice!
By the way I intend to LOOP with it so its not totally OT!!
