The baritone saxophone B-ONE from TREEPUR is offered with three different finishes: lacquered, brushed and lacquered, and plateado. All the baritone saxophones are subject to the METALAX treatment, which results in the relaxation of the metal and finally in the production of "round" and earthy sound. With the option "Singing Bell hammering", there is a possiblility to produce even more earthy bass frequencies.
