I mainly use this piece of kit as it has a very robotic vocal vocoder built in. I also use it for its other extensive effects like flangers and chorus effects. As with all Behringer equipement it has its flaws and after five years of owning this and having it racked its lost its left channel which is slightly annoying, as it renders the vocoder completely useless.
Like all rack units, it does something Great and others just ok. This has the best Pitch Shifter I have ever used. It tracks Guitar, Bass, Notes or chords. The Reverbs are stellar and the Delays very good. No self oscillation of you Delayheads. The Vinylizer is neat for making your guitar sound like an old record (33,45,78 you pick the speed!). I keep mine in the effects loop of my guitar head and it is truely a Gem. Purchased in 14 years ago and still have no issues.
