Non-standard Make & Model standard Mod Kit
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 standard Mod Kit (no HEVS) to match your trumpet. This is usually required with low production instruments, vintage, and antique instruments.
