Common Questions About the Bach 3491HCGP
Is the Bach 3491HCGP a cornet or trumpet mouthpiece?
The 3491HCGP is a cornet mouthpiece model. Cornet mouthpieces typically have a different shank and receiver fit than trumpet mouthpieces, so you should match it to a cornet leadpipe/receiver.
What does 1.5C mean on a Bach mouthpiece?
1.5C refers to the Bach cup size and cup style. On this model, it is a 1.5C cup with a medium cup depth and a listed cup diameter of 17 mm.
What is the finish on this mouthpiece?
The Bach 3491HCGP is gold plated. Gold plating on a brass instrument mouthpiece primarily affects feel, durability, and aesthetics. While the core sound remains highly subjective, many players find gold feels smoother on the lips, warms up faster, and eliminates allergic reactions to underlying metals.
