Aquaboy mods

[hoyager]

Hey there, I've just ordered 3 boards and am wondering if its possible to add a switch to cut the dry signal, so the pedal can be used as a vibrato with the mod mod, and as a send effect for dubs? Would the mix knob turned right up have this function?

Also, would it be difficult or possible to add some kind of tone control thats not just attenuating, so powered and boosting treble or bass which would affect the repeats?

One more, is there a good place to add a footswitch which bypasses the feedback knob and while held down, sends the pedal into self oscillation?

Many thanks
Andy
