I too, have tried all the numbers (again today) with no luck. My (Hi-Power) Stereo amp needs some kind of minor repair. I may have to purchase another amp soon ...bummer
Anyone talk to WW yet? I'm going to call tomorrow - may have issues with my Ultra, but not sure - may have been bad power at the club I played at - going to test it at home for a while, but I wouldn't mind sending it in for a check up.
