Finally got my Geyer single f/e/eb 4 valve put back into shape. This was a major cleaning, take down and resolder of all joints and patching 2 cracks. Before, the joints/knuckles were so leaky that you could actually hear the air coming out. When washing the inside filling it up with water would put drops out of any number of spots. Valves were in good shape but bearings needed tightening. Now, it sounds great, but the wire inside the rim buzzes. The tech did a great job and gave me a price on all the other work, but the rim wire is very expensive to do and not always successful (or so I was told) involving uncurling, pulling the old wire and then installing a new one and curling back over. It is much improved, I'll give you that, but that buzz on the last octave +/- is annoying. Are there other fixes? Ideas?

I went over this thing, probably 30 minutes a day (use this instrument to start my practice) and started gently putting a piano string wedge (rubber) between very close joints and the like. Finally found the spot and solved by putting a strip of leather between the tubes and wrapping about a 5" section with a leather wrap. Now it really plays great. Looks bad, but who cares?
