I did a bit of late night playing last night before bed, and everything was fine. I finished worked today, turned on my amp, saw all the little lights come on as usual, but no sound. I've tried two different guitars, three different cables, tried going straight into the amp, playing with all the dials, turning it on and off, unplugging for a minute, and even looked up how to do a factory reset and did that. Still nothing. I looked it up on the Blackstar forums, and it seems like a couple other people have had this issue with ID:Core amps in the past. But one of the was a brand new amp and the guy just got it replaced. Mine's 18 months old, so no more warranty. The other guy I found with a similar issue could still get sound through the headphone out, but I don't get any sound that way either. Aside from all of the lights working as normal, the only sign of life I can get is if I crank the master volume and gain to 10, then the background staticy noise gets loud enough to hear, but I still can't hear anything from the guitar. I emailed the shop that I bought it from and he basically said not to expect much from Blackstar. So I guess that's that last time I buy one of their products.
