As I transition from PODs to stomp boxes, this is the first distortion I buy. The online reviews are good. I recommend Pete Thorn's sound test as it's a demonstration in detail. After trying it out myself I cannot but agree with everyone. It's NOT a improvement of the old DS-1. It's a whole new beast! Sounds great, responsive, good dynamics, clear low end (not muddy) and sweet high end (not screaming). What more could you want? It makes me wanna buy the OD-1X too!
