Denis Wick enjoys an international reputation as a virtuoso trombonist and brass teacher. He was Principal Trombone of the London Symphony Orchestra for over 30 years and was for many years a professor at the Guildhall School of Music and Drama. Mr. Wick became interested in mouthpiece design when he evolved his own mouthpiece after many years of careful experimenting. In consultation with Britain's finest brass players, Denis Wick began to develop better mouthpieces, using both traditional and new ideas. The new heavytop models for trumpet, cornet, French horn and trombone use a completely different principle in not feeding back to the player the vibration of the instruments, transmitting all the energy through to the bell. This gives a much more powerful sound when needed, more security in the high register, and more control and focus in all registers.
