would this work? what I want is to be able to switch from a clean to a distorted channel to a tuner (for silent tuning) at the push of a button. the only thing I can see wrong with this whole thing is the delay pedal... are there any delay pedals with two inputs? or should I find something like a volume pedal, plug both channels into the volume pedal, then the volume into the delay (and the delay into the amp)

I actually don't have the pedals (or the money) for this sort of thing right now. but I like to dream...
