I picked up a couple of Ibanez DM2000's. The problem is that i get no output from either one of them. I'm beginning to think i'm doing something wrong. Does anyone have any experience with these units? I would think its as simple as guitar--> input, output---> amp. When i do this i get a clean signal path, no delay. When i hit the bypass on the 2000, it cuts off. I can't think of 2 seperate delays doing the same thing. Is it something i'm doing?
