I'm new to the forum, was just wondering if anyone could help me. My Behringer gets very fuzzy sounding with the EQ on, even if all the bands are set to the lowest setting (-12) and it gets super fuzzy when I hit the "Shape" button. Is this just the degrading quality of the amp over time being amplified more, or could I just open it up and check some connections first? This is unplugged from any instrument, just to rule out cables and inputs. Thanks in advance!
Are you reporting that it makes noise or that it is distorted? To me, "fuzzy" means distorted.
If it sits ther just making noise, it is almost always a noisy op amp. Go down the board and scope the output pins of each op amp. FInd one making noise.

by fuzzy i mean that it's making noise, sorry. im not super familiar with amps though, could you give me a slightly more involved description of the process? what do op amps look like? thanks for the reply, though!
Op amps are the little multi-leg integrated circuits. Behringer sometimes uses 14-leg TL074, which has four op amps in the one IC. Otherwise all the 8-leg ones have the same pin arrangement. They could be any number of types, but probably are 4580 type.
Yeah, that's probably it. Everyone knows all the other brands never fail and ICs and other parts don;t go bad in them.
oh relax
well, actually i AM saying that, kind of. three behringer products that i have owned (and enjoyed) for SHORT lives have brought me to this conclusion, one of which being a k900fx, this unit's little sister. there are without a doubt good and bad units, and components destined for failure in any product that is made. however; i have amps that have been (not lightly or gently) used for 15+ years that still work fine. but i've never had a behringer product last (never leaving the studio or going to gigs) more than a few months past warranty. you get what you pay for. i'm sure you feel the same way about SOME brand of product you have encountered. it just seems to me that behr. seems to show up alot as one of those brands that's better left to novice players who aren't to the point yet where large budget, good pro gear is needed. i won't gig with any product by a budget brand. would you want a mechanic working on your car with parts made from inferior material? i'm sure venue owners wouldn't be big fans of a band whose gear went down mid song, either. hey if you want to use junk gear, by all means, go for it. just don't expect it to perform like pro gear.
