To be honest, I needed a silver plated screw for my selmer, and I couldn’t find one at all. It seems like they were all sold out around the world, so I broke down, and I bought this. To be honest, I never really put too much credence into the idea that a single screw around the neck would make any difference, particularly if your neck is fitted properly I’m not sure that it makes a world of difference to the audience, but to me, I could hear a difference. I did a/b this against another selmer screw that was made for the the horn and against another well-known Japanese manufacturer of aftermarket parts. Between the three I did think that the yanigasawa was slightly better. It was also significantly less expensive than the other Japanese aftermarket makers part. So, I am not going to tell people that this is a magical thing, but for me, I could tell the difference. Even though it was slight, it was apparent.
One last thing I would add, I did find a significant difference when you added the different tonal booster components to the screw. That surprised me more than anything. I did, from a practical perspective, like the size of it. It is very easy to clamp the screw down tightly without any issues.
