The creation of the BERP grew out of the concept of mouthpiece buzzing which has been used for many years as a teaching technique for brass players. The Buzz Extension Resistance Piece, or BERP has been used by brass players for years - and now is better than ever.
* New adjustable resistance dial slides over four holes to let you tune the BERP to any resistance you want. Beginners can set it to the resistance that matches their ability.
* Side-by-side design lets you switch between playing and buzzing instantly. You can efficiently work out passages through playing and buzzing more easily.
* New adjustable clamp fits around the receiver opening of any brand or model of instrument. If you play a brass instrument, there's a BERP for you.
