On a King C-Melody sax, with a Jody Jazz (alto) HR* 9M mouthpiece - rather open tip - and a Rico Royal #2 BASS Clarinet reed... Rather eccentric setup, but, apart from the tip opening (.105" ?), quite a bit of similarity to the old 20's setup... The bass clari reed is an excellent fit for the JJ alto mouthpiece table/tip profile.
AS I now play Bb tenor, I could be searching for a slightly more unique and/or individual C-Tenor sound than the normal 'tenor mouthpiece' type !
And now for something completely different - just a bit of a waffle on tenor sax, decades ago, way down in the mix, at a recording session in Wokingham - Peter Howe was the singer. Who dubbed that squeak in ????
