Some time ago, I picked up a used Clarus 1 head from a fellow talkbasser here. It lived pretty much at home, as a second/backup rig until a rather spectacular meltdown. I pretty much wrote it off, but thought I'd take it to Tim, the amp tech at Full Custom Music (fully endorsed and fantastic) to see what it would take to get it back to life. It never crossed my mind that the amp might've been under any kind of warranty. Well, Tim called AI, they said "send it in, it's under warranty" ... I still didn't believe it. Well, the other day it came home, repaired power supply, replaced preamp - they even upgraded some of the circuitry. Zero cost. Looks and sounds better than new.
All I can say is that the music industry has become increasingly consumerized and throwaway ... the days of professional standards and high quality construction seemed to have been lost. Not AI. My next amp will be an AI product, for sure. The new Flex is particularly appealing ... sexy as hell.
