Having several (vintage) mouthpieces with different shank bore sizes gave me some issues with my neck cork. The smaller ones easily destroy the cork thickness, making it difficult to play the wider ones. In order to solve that issue I bought some monthes ago a second neck for my Selmer SBA (Super Balanced Action) of 1952. Now one neck has thinner cork and is for the small bore MPC's, the other neck has thicker cork and is for the wide bore MPC's.
What surprised me is the difference in sound between the two necks. In order to make that more clear to myself I recorded some takes using the same mouthpiece/reed combination on both necks. Out of two tracks I compiled a "Selmer SBA Neck Comparison Blues" of 10 chorusses, played on two vintage Otto Link mouthpieces. I just created a small video with pictures of the necks and mouthpieces and put it on YouTube. See this link:

By opening the description under de video you get a time index, which makes it easy to jump to a certain part of the recording.
Some details on the equipment:
- Neck 1 is my old SBA neck. It has no lacker and is a bit higher then neck 2.
- Neck 2 is my new SBA neck. It has more lacker and is a bit lower then neck 1.
- The first 5 chorusses are played on a vintage Otto Link Florida no USA 10* with a La Voz medium reed.
- The last 5 chorusses are played on a vintage Otto Link Tone Master 8 with a Fibracell 3,5 synthetic reed.
My conclusion is that neck 2 sounds considerable darker then neck 1. I expect that the main reason for the difference in sound comes from (small?) differences in shape (bore, bow, ...). I don't think the presence of more or less lacker has anything to do with it.
Just posted this clip here for information. Please don't bother to much on my playing, I'm just an intermediate player who likes to make these kind of comparisons .
