I don't often go into PMT in Norwich as I'm not keen on the atmosphere but I did today and majority of the basses and amps didn't have pricing, telling me to enquire at the till. I'm not in the position to buy gear but if I was, it would have put me off.
Pleased to hear that. I've been considering changing my strings recently (I've had the same set of Cobalt Flats on for coming up to 2 years now) and I really can't think of anything else to swap to. It's going to cost my a fortune next month!
Old age? Worn out? If it was me, I wouldn't be concerned if it is the only fuse to have blown, if it keeps blowing a fuse, then I'd be concerned.
