I would like a mini-pedal similar to the two mini SHO boosts that I've got from This1smyne, but I would like it to have 2 stomp switches on there. It would essentially be a dual function pedal with the left side acting as a tap tempo for the Dual Tap Delay and the right side acting as an on/off switch for an expression pedal for the M9. The tap tempo side is easy, but is it possible to build an on/off switch for the expression pedal, and if so, what would the behavior of the M9 be if the expression pedal is off? Here is my pedalboard layout as I'm protoyping the signal flow and you can see the little boost pedal right above the expression pedal. Can anybody chime in on that right side of the circuit? In terms of the materials, I know that it'll need an enclosure, 3 jacks (1 from DTD, 1 from M9, one to the exp pedal), a momentary normalOff switch for the tap tempo and a latching DPDT for the right side. I won't need an LED so power is not an issue. It's just passive... although an LED for the exp pedal would be helpful.
