It's driving me crazy, various patches give a lot more buzzing than others (especially fuzz effects) and I'm not sure what the problem is. I've tried different bass guitars and still the same. Touching the strings or Jack input on the zoom quietens it. Can't hear the buzzing when just through my combo amp though.
Is it because the zoom is more sensitive than my amp or is it possible that I have a faulty zoom?
Any help much appreciated
