Well, in my opinion ANYTHING is good (or bad) for noise making... it is only a matter of the way you use it and the structure of efx chain. I just recently bought RS second hand from some guitar oriented player (blues... I think?) who probably didn't find it very fascinating. Ravish Sitar is basically made for guitar but I found it being more interesting when combined with synth and Weird Sound Generator. Some You Tube -videos suggest also that it has a potential with bass guitar. It is probably more useful in drone stuff than hard in-your-face PE noise. But as I said, I just recently got it, so haven't had too much time testing it.
