@EBS_freak There used to be a couple of guys working in PMT in Oxford in a band called Twin Jet Superstar - I remember loving the guitarist's playing. Just been googling and it seems that the fella is called Dave Smart. Seems like he's moved on to pastures new and now has a repair business and got something to do with Oxford Guitar Gallery. There you go. The thread has rekindled some blast from past memories for me!
Dave Smart is my amp tech. His web is Dave Smart Guitars. He's a lovely chap, so helpful. He's done much work for me in the past.
He also builds guitars ( not sure about basses ) and they're stunningly made
When my TE Mark V GP11 combo had a graphic and eq switch failure, he fitted the new switches ok, ( although a bit of a bar steward , apparently ) but i also wanted to keep the green TE outer covers so it still looked original, which according to Dave was a right pain, but he did it. He did a service too, and then a PAT test, which he sends to Gardener Electronics, an official PAT tester.
Dave also serviced my Kustom Groovebass 1200 head, and did some remedial work to the circuit board, that some earhole had managed to murder
