Lets say you had one of the line6 stomp modelers like the mm4 and you wanted to use an expression pedal with it but you wanted something a little bit different. What would happen if you used an all in one expression/volume pedal such as the Boss FV-300L so you conect it as a volume and expression but the volume only has a slight or half volume decrease when you use it so bassically as your volume decreases your effect will change into the other setting in the unit. Would this work? Sound good? Or is it the stupidest idea you have ever heard? Thanks in advance.
