Wow, You always manage to sound like a dick no matter what thread you're active on. Your I know all and always what's best brand of condescension takes away from the knowledge and experience you have to share. Sure there's no standardized bore size, but the alto bores on the early models were too small and they made a change in later runs. The original, per Rico, was the same as the Meyer they modeled as their base. No need to be mean to unknowns on the forum, especially on legitimate questions.There is no 'standard' neck cork size. Most mouthpieces have different shank bore diameters, including examples of the same model. The entire question is ridiculous. When you try a mouthpiece that's too tight for your cork, you have to sand down the cork to even try it. Its a risk, but unavoidable. If you like it, you're done. If you don't like it, you now need to install a new cork. The idea of boring out an expensive mouthpiece to make it fit a cheap neck cork is not something I would ever recommend because I believe it can change the mouthpiece. Plus, if its a 'trial' mouthpiece you can't alter it anyway unless you keep it.
Rico/ d'Addario doesn't even make metal mouthpieces...I played at least 10 different select jazz models on tenor, some were 1st run stock, and all were excellent in craftsmanship and playability. I've heard plenty of people say they don't prefer rico pieces, but rarely if ever that they have poor craftsmanshipor quality control.I don't know about D'Addario current production, but the early complaints about tight bores on both anniversary HR alto and metal tenor kept me from trying them, as well as other issues (duck bill beak, burrs on window, uneven baffle profile, irregular rails) requiring refacing and fine finishing of brand new factory mouthpieces.
Regarding two custom tenor MP from a prominent maker I had a machinist hone the bore (outer ¾") .004" of the metal MP to fit the cork with same compression as the HR piece since I was playing each every day to compare and contrast over a long period. Otherwise the HR piece would slide right off after replacing the metal.
The honed area is only where MP is on the cork, so I can't see how it changes the chamber dimensions or any quality of sound.
The maker suggested an alternative was to build up the HR piece ID with nail polish, but the metal one was tight compared to my other pieces so adjusting it is what I did.
Thank you, yes--I was confused and have corrected my post.Rico/ d'Addario doesn't even make metal mouthpieces...
