i knwo michael uses a boss vf-1, but is that what was used on that track? i like the real time advantage and ive considered purchasing one. however, im not to sure. would it interfere with my amps settings? i dont plan on using it as a pre, more for effects that i can control with the expression pedal. how would i rack mount this thing? any other info or help is welcomed. also i did a search and couldnt find my answers.
