The B&S 3137 Challenger II trumpet is the logical step in taking the Challenger Series to the next level for the most ambitious players. With a slightly different lead pipe taper and bell design, the Challenger II has less resistance and a different lead pipe and bell flare combination.
The 'Phil Cobb LSO' model features a custom bell and leadpipe developed with Phil Cobb to satisfy his requirements playing in the LSO.
