GR Trumpet Mouthpiece 67L, silver-plated finish. GR, used by a trumpet player in the Chicago Symphony Orchestra, is a mouthpiece that produces a dense, full sound. There are scratches on the outer rim. There is no problem with playing. I found it easy to blow and didn't feel much resistance. I prefer a bit more resistance, so I bought it used but am selling it. It's priced affordably due to the scratches. Returns are not accepted to prevent switching of items.
