HK Factory Trumpet Mouthpiece Ring - Double-Sided Hammering

A mouthpiece ring developed with a new concept. Focusing on resonance and reverberation, it achieves stable sound from low to high notes. For trumpet (inner diameter 11mm). Made of soft material, so please adjust the size by hand to fit your mouthpiece before use.

Personally, I feel it produces a thick sound, as if using a heavy-duty mouthpiece. Yet, there is virtually no increase in weight, so there is no discomfort when holding the instrument. Plus, it's incredibly satisfying how easily high notes are produced.

Of course, please understand that compatibility with mouthpieces and instruments may vary. It does not pair well with the New York classic.

《 About Silver950 MP Ring 》
While common silver accessories are often made of silver925, this product uses Silver950, which has a higher purity. It is developed and designed with the following four concepts, incorporating heat treatment, hammering, and special processing:

① Sound tightened by hammering
② The resonance of solid silver (intentionally creating gaps for resonance)
③ Sound changes due to heat treatment
④ Realizing these three elements in a detachable form

《 W Series (Double-sided Hammering) 》
・Width: 5mm
・Aims to improve projection without drastic changes
・Aims to change only the sound without significantly altering the playing feel
