So it seems that depending on how you look at it, it's either a "feature" or a "mistake" that on my Genz Benz Black Pearl 30, the effects loop is designed to be used with rack gear, NOT pedals. I recently purchased this amp used, and in reading about it discovered that other owners were complaining about poor sound with pedals in the loop. One person even communicated with the amp designer Jeff Genzler directly: I tried putting a pedal in the effects loop and it caused a rather drastic change to the sound. It was almost like the sound was kind of like some heavy dose of reverb was being applied to it (even though I turned the reverb all the way down on the amp). I will experiment with the levels on the pedal and try some other pedals as well, but I was wondering if you had some insight on this. ***Our Effects Loop is designed for true line level effects----more like outboard effects. We designed this amp to be very pedal friendly in the front input section so we always recommend that you place pedal effects in the input. So... Any suggestions on what I might be able to do to get pedals to play nicely with this loop? Obviously I could go to rack gear, or move everything in front of the input, but I'd really rather stick with how I'm doing things, with delay and reverb in an amp's effects loop.
