Well for Behringer, their stuff can be useable OK but when pushed you start to notice stuff like really much noise, really shitty pots, really weak solderings and basically just weaknesses all around.

I have a lot of Behringer stuff, and usually end up in tossing them. The last one was a floor version of the V-amp system, utter crap...tossed it in the bin...also bought the WAH pedal...works OK, except I broke one control in 2 days and it is rather noisy as well...kept it anyway. Maybe useable for something. I also use one of their mixers, which when used in recording side are a nice way to destroy any purity of a signal, but are useable for listening side mixers in some situations.
