A few weeks back, whilst adjusting a tuning slide on my baritone, one of the soldered joints came adrift. I tried resoldering it myself, but - even with a 100W soldering iron - it came out looking like pigeon poo. That slide (the one without a water valve) had always been a bit stiff. After my attempted repair, if anything it felt worse. So I took it along to Alan Gregory's in Manchester. They sorted it at what I thought was a very modest price, and I went in to collect it. Opened the case, looked at the slide; looked more closely; looked VERY closely; damned if I could see which side they'd repaired! Got the baritone home, took the slide out and looked at it in bright sunshine - I still don't know which side they'd fixed! Five Gold Stars, Messrs. Gregory's!!
