The Stop Rod Pedal F Stop for Bach Stradivarius Trumpets allows the player to facilitate a pedal F by extending the range of the trumpet by a full half-step. The pedal F note is used when playing instrumental parts originally written for trumpet or cornet pitched in low A, G, F, E and Eb. The Stop Rod Kit features a locking stop nut and spare, plus 5 O-ring bumpers to adjust intonation and reduce noise, plus an Allen wrench for quick and easy installation. |
