This is my new custom DIY.
The idea : use a BossFV500H Foot Volume and Expression Volume. Initially, you can't use both because this is the same potentiometer (a double potentiometer) so if the volume is down, the expression is at 0 and if the volume is up, the expression is at max.
My idea : use a footswitch like on a wahwah pedal to switch volume to expression fonction.
I have add a LED when the Expression mode is engaged. The volume is at max (truebypass of course) when the expression is engaged.
