What are other users doing for their noise gates?
I'm finding to avoid feedback at normal rehearsal/gig volumes I'm having to set a 4.1 gate on the first stomp with the threshold at maximum. Seems a bit extreme, although i guess i had to set things up similar with a real amp+gate.
do you mean microphonic feedback (aka howl, squeal etc.)?
that is 'caused' by mirophonic pickups.
