Haven't actually tried the PW-2 but if you do a search about the PW-2 on this forum you can get an idea of what it may sound like. I just figured since its out of production and one of the shortest production runs for a Boss pedal, it might be worth something.
PW-2 is fine if you like a grungy distortion, most people don´t like it very much but I think it has a nice raw distortion, even if I´m a crunch-player. Nice colour too…
