So, day two of owning my WA76...I turn everything on and notice the VU meter is not moving. I play with the settings and poof, there's no compression at all. When I unboxed it last night and hooked it up, everything was working fine, in fact it sounded AMAZING! Needless to say, I'm pretty bummed right now, as I have a gig this weekend and now am going to have to use my Keeley Compressor Pro instead. I just finished e-mailing WA's support, so hopefully they have some ideas as to what could be happening. I'm hoping I unwittingly activated some sort of bypass mode, but if it has one, it's news to me! Anyone have any ideas? Literally nothing changed from last night to tonight, except I was playing with the "all buttons in" mode and tweaking other settings. The VU meter does not move off of zero and it passes a dry signal through with no issue. As I crank the output it does get a little hissy, as I would expect.
