Meet the first in the line of Phil-Tone Soprano mouthpieces. The Sapphire is the small brother of the extremely popular Sapphire Tenor piece. It has a concave sidewalls, an enlarged oval chamber opening into the bore and an undercut table to add depth. It boasts what few soprano pieces possess. Ease of intonation, control and a soprano sound that is not abusive and abrasive to the ears. It has excellent focus and a core that keeps you coming back. Like all Phil-Tone pieces, each is made by Phil to meticulous standards. Each piece is also play tested for response and musical quality prior to leaving the shop. Do yourself a favour, play a Sapphire. If you double or play soprano full time you will find it a joy and a worthy addition to your setup.
