Aaaaargh! Any body know of an electronics wizard who can sort out my bass amp. Warwick 150 that every so often just completely dies, as if you hit a note and then slowly turn the volume down. Leave at a couple of minutes and its right as rain. Had it in with 2 so called experts, neither of whom could find any thing wrong with it. Trouble is I can't trust it now, so I've had to splash out on some new gear, but I really like the sound this Warwick combo gives (Teutonic Technology, vor sprung durch and all that stuff). Had it 12 years from new and would like to keep using it. Any recomendations gratefully received.
