I took my brand new amp on a jazz gig here in Detroit at Bakers Keyboard Lounge and the amp worked for 1 song.
After that the sound cut in and out and the power light flickered on and off.
I called a representative and they explained that the power regulation may have triggered the internal protection circuitry on the amp.
I then placed a call to service and did not get a return call.
I have played this club for over 20 years and have never had an amp fail due to "bad power" and btw the entire club was operational with the exception of my amp.
Now to stay within my return policy period I have to ship the amp back at my cost........
