THEN the ears take over. No real noise problems. Parametric EQ adjustments can vary tone wildly. The Analog Delay and Stereo Chorus make this unit shine. 10 Never had a single problem.
Foot pedal works like a charm as well.
This unit will add some delicious warmth and space to an electric guitar tone. I was wondering if maybe the fx loop's return buffer had a problem. I wish it had the tube screamer that the ue-400 had, but other than that, I'm very happy with it. It's four discrete effects, plus an external effects loop, in one two rackspace unit with a remote footswitch. I got a manual from Ibanez, but it doesn't help much.
