Warburton Backbore B 5 for Trumpet
Warburton Backbore B 5 for Trumpet, tight to medium (4-6). With progressively less resistance, these models produce a bright and very projecting tone. The #5 is by far our most popular with strong lead players. The only difference at the B-Series is in the external dimension which is slightly larger and causes a subsequent increase in the GAP.
