Game changer for rotary trumpet

German in Hawaii 10.06.2026

Breslmair mouthpieces have always been an enigma until I discovered this backbore for use on rotary. Read Dr. Harms description. The Breslmair mouthpiece bible helped to dial in a combination for me that was beyond expectation without having to buy a fortunes worth of pieces. The only trick has been the rim. Careful reading of the bible helped there too but ended up buying a few. This backbore does what they say and changed my opinion about Breslmair. Great gear once you know WHAT to buy. Makes playing rotary a great joy to get a sound hard to replicate on a piston IMHO
