I just bought a new Ampeg SVT-7 head and while installing the rack handles the screw head sheared off due to the screw hole not tapped properly. This left the threaded portion of the screw inside the rack handle and the screw head on my workbench I had just registered my warranty on Ampeg's site so I thought I would try their customer service support rather than going back to the vendor (Guitar Center). Within 24 hours I had a reply back to my email by Rebecca requesting additional information which I provided. She quickly replied to my email stating a new rack handle will be shipped and a tracking # forwarded. I did not expect such good service and quick response and wanted to pass this along. I was a bit uneasy pulling the trigger on the SVT-7 after reading up on it here but luckily got a revision C which supposedly has the limiter issue ironed out. I am pleased with the amp so far. It is very toneful and very very loud . The 5 year warranty gives peace of mind especially now knowing they will stand behind it. I had a SVT-3 about 12 years ago that sounded good but could not cut it in the volume department. At that time if I had an issue I would take it to Ampeg right here in St. Louis which was nice but that was pre-Loud. Anyway, sorry for the long post and thanks Rebecca in customer service, hopefully I will not need to use you in the future!
