The ACB AOS backbore was developed specifically with the C trumpet in mind, but will still fit and work great in a Bb trumpet. The heavier backbore helps to add some warmth in the sound and some security in the slotting.
Each backbore has some insertion marks, but is otherwise in amazing condition and ready for a new home!
All of our backbores/tops are on Warburton threads, making them compatible with the majority of the modern market.
