I just acquired one of Phil's "Eclipse" Tenor mouthpieces in a trade with a friend. I had been playing the same Brilhart Streamline for around six years (a record!) but when I played the Phil-tone I knew I had to have it. Many years ago, I was a fervent and dedicated mouthpiece *****, playing everything in sight (mostly Links) and changing from one to the next every few months. I didn't think anything could get me off the Brilhart though. I love that piece.
But Phil has done it.
If you're looking for a great mouthpiece (at any price), get a Phil-Tone. I've played dozens of HR Otto Links from all vintages, and most of them don't play as well as the Phil-Tone, although these days, the ridiculous price of "vintage" Links would suggest that they play themselves, tuck you in, and then wash the dishes. There is the added advantage that if you drop your Phil-Tone and damage it, you can buy another one without resorting to a mask and gun.
$225 is DIRT cheap for a piece of this quality.
Phil doesn't know me, and hasn't asked for my endorsement, but if he wants it, here it is!
