So far I'm noticing it from the regular Tape Delay and the AC Flanger. I've just bought the thing new, have a gig next weekend and wondering am I missing a setting? When I say volume drop i'd say about a 20-25% drop when that effect is kicked in from when it's kicked off. I've tried putting them in different banks with the same issue, so it appears it's the model and not the bank.
I'm using in the the loop of both an Blackstar Club 40 and club 100 half stack. Same issue.
Am I missing something?
