So at my Jazz class on Saturday, my WT300 head clicked and then stopped - no sound! The fan came on loudly and there was a very quiet distorted bass sound coming out when I played - but basically that's it. Of course I checked that it wasn't the bass by trying this through somebody else's amp. It came back on intermittently at first, but now has really died. I have other cabs - but only one amp - so it's a bit of a downer. So my question now is what to do? I contacted my insurance company and they said my policy doesn't cover this - only things like theft, accidental damage etc. I phoned the local amp shop and they don't do repairs - although they gave me a number for a guy who does locally but I can't get him on the phone - although I have left a message. I phoned Overwater where I bought it - but they have their phone on answerphone as well. So - has anybody had this problem - I have had the thing for 3-4 years - do they last longer than that? Any ideas what is wrong - how expensive it is to repair etc.? Any UK people - London-based maybe, who know where does repairs and how expensive - any recommendations? I am at a loss now, for what to do next or be stuck with no amp!
