Solid wood finger caps for Yamaha trumpet. These are lighter weight than standard finger buttons and are all wood construction (except for the screw which is solid brass).
These use a Yamaha M4x0.7 thread to mount. This is universal for Yamaha instruments, but the cap depths may vary. Your technician may need to fine tune the height with felt or even adjusting the height of the cap.
This is a soft launch with limited supplies! I am only making these available for Yamaha in limited wood options to begin with, so get yours now at the introductory price if you want to be part of my feedback crew for these.
