Hey @Vladi !

Something even more stoopid !

What if Your expression pedal had a pot connected to Expression 1 and the switch connected to Expression 2 ?

With a little tinkering on the QC, the switch would bypass block 1 & turn on block 2 at the same time (toggling) and the pot would control whatever block is on.

… hum hum, I think we just re-invented the wheel : the Mission Engineering expression pedal with a switch… For a couple of dollars/pounds/euros (shows how you can make a huge profit with a 10K pot, a switch and a wah enclosure, some nice paint and hell of a marketing team)
