I would suggest you work with Axiom to locate the problem. You are 2 years into your warranty which means if something is busted, you can get it fixed for free. That includes shipping both ways IMO because you paid a tidy sum for your Axiom gear.

Three years into my Audiobytes the amp developed a problem and I neglected it and now I have no one but myself to blame. Well, that's not quite true. I blame a certain individual with the initials of TC.
