My BOSS FV500L volume pedal is connected to my Boss ES-8, which sends a MIDI CC (input volume) to the second, last in the chain, H9 (that is allways on). It works absolutely amazing, with any artifacts, but with a couple of positive side effects: At first I don’t have the volume pedal in the signal path, and second: I can use the pedal on a preset basis for different purposes (expression, for example) as well.
