Yep. I had one that I bought to trial and it's a great pedal.
The noise gate is fantasic but equally necessary at most gain levels.
It achieves a wide variety of metal tones and the harmonic content is really detailed; think dime's squeals on floods solo.
It works very well as both an in front of amp pedal and a preamp. Obviously better as a preamp though.
The features and build quality are of a very high standard and I would love to see more pedals from James brown. Hell, the man pretty much created the 5150, xxx & JSX.
