Non-standard Make & Model Finger Buttons
While we offer Finger Buttons for hundreds of brands and models, there are some instances where we will need to measure your existing parts. Add this item if your trumpet is a non-standard size requiring samples to be reproduced. Jason will need to measure thread pitch, shoulder heights, diameters, etc. to make you a custom set of Harrelson finger buttons to match your trumpet. This is usually required with low production instruments, vintage, and antique instruments.
