Hey guys,
So, I'm guessing that this would be pretty easy to set up on a decent multi-effects unit, but I have an idea about a stand-alone effects pedal that (in theory) would give an infinite sustain type effect. Basically, a volume pedal and a delay pedal in one. I'm not too technical, so probably won't be butchering my pedals to try this out, but would work something like this:
The expression pedal would control both the volume and the feedback of the delay at the same time. As the volume swells in, the feedback increases up to infinite, so that once the volume swells to maximum, the delay will be sustaining the note for as long as you want. As the expression pedal is rolled back, so the volume and the feedback both decrease back to nothing (or a set feedback level).
At the moment, I'm using a volume pedal, delay and a EH Freeze in various combos to get this sort of effect but, I dunno, doesn't seem that complex to me...
Any tech-minded people out there want to shoot this down (or build me one)? Or does something like this exist somewhere already?
