Nope, I haven't even heard of it.
Anyway, what kind of amp do you have? If you have a solid state, forget getting an overdrive pedal, as it is a big waste of money.
Anyway I would reccomend the Visual Sound Jekyll & Hyde Ultimate Overdrive pedal. It is freakin' sweet, I tried one myself. One side replicates the tubescreamers overdrive, and the otherside has a stronger distortion. It's like two great pedals in one. They have great feedback(no pun intended ) and are n't as expensive as say, a TS909.
