It seems the only negative feedbacks about this amp are from people who don't understand how to use the input level and output level knobs in the rack. If you hear any complaints about noise, it's because of that and their lack of desire to mess with that. You can't put both up to 10 and overdrive your signal. All 3 of these units are excellent.

haven't had to use it cause it's a quality item. so I give it a 10
