What does a schmitt trigger sound like with a guitar running through it? Theoretically speaking, shouldn't it make the guitar sound like a square wave synth? Unless I'm not understanding it right... :?

Yes it sounds "synthy" But you no longer have a natural decay, (Schmitt triggers have a set trigger level.) I spent a week or two on this two years ago. Tim E. has some stuff posted if I remember correctly.

Ooh, sounds cool. The lack of decay makes sense. I've been looking for something to do with this random 555 timer I have, and got an idea whn I read about schmitt triggers. Gotta go do more research. Stuff to follow, hopefully.

Schmitt triggers, multivibrators, sounds like fun! :twisted:

If you apply variable amounts of feedback from the inverter (comparitor) output back to the input, you can vary the level of "Schmittness", a.k.a. hysteresis. ;)

To get some decay back, you can always mix some dry signal back in.

That sounds better than hysteresisisess!

remember that the schmitty Schmitt trigger will react only to the positive part of the signal, so you'd need two, yup a Schmitt push-pull-er, only the negativer part of the signal would have to be inverted so that the trigger could do it's job and then inverted again (voltage-wize, not talking about an inverter!)
