In addition to crafting world-class musical instruments, Bach endeavors to supply each musician with a mouthpiece that perfectly fits their embouchure. Trombonists who require a strong fundamental tone and carrying power that blends well with the rest of the orchestra gravitate to the Bach 6-1/2AL. Within the mouthpiece’s large shank, the 0.261-inch "G" throat and #420 backbore team to deliver a sound that’s perfectly suited to the rounded, mellow sounds of the Teutonic (German) tradition. Players rave about the uber-comfortable medium-wide rim shape that works to improve endurance. If you’re regularly performing pieces that require a consistent smooth sound, be sure to add a Bach 6-1/2AL to your mouthpiece collection.
