The Buzz Extension and Resistance Piece for Trumpet (or BERP) is an innovative design which allows the performer to practice solely with the mouthpiece but with the same resistance and valves of the instrument. This clamp on device is perfect for practicing and for rehearsals.
Full AdjustabilityThe clamp for the BERP is extremely versatile, meaning it can fit on to the leadpipe any model of instrument. This makes it a really beneficial tool for people with multiple instruments. The adjustable resistance slide means that you can adjust the four air holes to match the resistance of the performer?s instrument. This makes the BERP as realistic as possible to the instrument itself.
