The Lab tech that repairs it says he sees the SVT 4 Pro in the shop all the time. He even over orders parts cause he knows that he will be repairing these things in the future! There is a 5 year warranty, but what good is it when you have to wait weeks at a time to get it back?!?!? I bought a high dollar amp thinking it would be durable and able to handle the rigors of weekly gigging. My old Crate Head is still more reliable than this (yikes! same company STL Music). Nothing is more frustrating/embarrassing/aggravating than performing in front of a few hundred people and have your amp go out.
