We already make a great Conn 12M neck, and this neck works like a charm for anyone who plays their vintage horn with vintage mouthpieces. However, Conn 12M players who prefer modern mouthpieces are well aware of the troubles of that combination: sharp intonation or mouthpieces that wobble just at the edge of the neck with no stability. Traditional neck extensions can leave you with flat palm keys. Traditional mouthpiece extensions make it so that you can't switch the mouthpiece over to a modern horn, and you need extensions on all of your mouthpieces. Curt Created the 12.5M neck especially for players who use modern jazz mouthpieces, which have shorter shanks than their early predecessors. This neck is longer with an adjusted taper to offer the best possible intonation and huge tone with premium mouthpiece stability. This is the pet project of a lifetime Conn 12M player, and there has never been a more sublime neck upgrade than the 12.5M. You're simply going to love it. Available in a variety of finishes. There may be a 4-6 week waiting period depending on availability.

"Hello Curt- The neck is absolutely great ! It has a big sound, easy to play and correct intonation :-). Most importantly it fits in to the receiver like it ment to be together. I appreciate the exact fabrication ! I am happy to do a business with you. In case you are in Europe, since I saw you travel a lot, I’d be happy to meet each other. Have a great day, you made my day :-)
My very best,
Jan Provazník "
