Just a couple of volume pedal ideas I had; To modify something like the Hotone volume/wah, and instead of having it manually switchable between a wah and volume, to use the built in footswitch to determine what mode its in.
1) The first idea I had was to have a volume pedal with a built in footswitch (like a wah). When you use the volume pedal normally its between 0 and unity gain. When you click the footswitch a boost is engaged.
2) The second idea I had was to have a volume pedal/expression pedal in one. It would have in/out jacks for the signal, then and additional TRS jack for expression. When you click the footswitch the pedal changes to become an expression pedal (and the audio signal just goes straight through).
