Re: Key clamps?
I bought and used key clamps on my alto for awhile, until I spoke to my repair man about them. However, after hearing, "Keyclamps? Repairmen love them - they provide plenty of work.", I stopped using mine. When I quizzed my repairman about clamps, he spoke about damage to pad seats from excessive clamp pressure. Perhaps, as Saxman has said, a lighter pressure would be ok. I might try using them again with a lighter pressure setting. On another note, I too love the Protec propak case for my alto.
