BRASS: slides or mouthpiece are stuck, valves stuck or sluggish. DO NOT attempt to remove it yourself using anything other than penetrating oil and fingers. NO TOOLS! If you feel the need to tie one end to the bumper and the other to a tree, it's probably time you contact me.
TROMBONE: any slides are stuck or sluggish.
WOODWIND: any discolored, stuck, brittle (hardened), ripped, or moth eaten pads should be replaced. All notes should be easy to play. Woodwinds should have an annual checkup.
