I’ve got one of the old triangle ones with the music man branding on it that I would consider selling. Let me know if you’re interested and make me an offer I can’t refuse!
These ones are a bit smaller, I have two of them labeled as "Sterling by Music Man" and one with "EBMM". They fit perfectly with the shorter headstock. They are not rock solid but when you are carrying the guitar by yourself and don´t throw it into vans, there should be no problems
