I bought a set of these from GC, after 2 gigs one is broken, cuts in and out! Seems like a solder on the PCB. I can't get through to AA support to get a replacement.

Today I went to GC and bought a 3rd unit, get to my gig hook up plug it in and flip the power switch! NOTHING? doa!

What is going on with these and how do i get them replaced or fixed"?

Have you called 800 322 6337? ask for service. from 8 to 4:30 pacific time
