Okay fellow players,
How about that gap adjustment? How is it done? In a reaction to one of my posts in the "for sale" area, someone suggested adjusting the gap to improve my flat upper register. The higher I get, the worse it gets. My high B's and C's are just to flat for my taste. Anyone who can send me some wisdom on this topic?
Jeroen.

If you are talking about the Gap in your receiver between the Mp and the leadpipe you are going to need to take your horn to a good repair man. I think this is often times one of the most over looked parts of trumpet design / repair. The gap plays a very large role in the way the horn responds slots and articulation.
TopGun or eclipse are you out there

Jeroen, you might want to go to this page and read all of the info from the various links. It's about as much info in one place on mouthpiece components and their effects as I've ever found. Pay particular attention to the discussion on backbore. grmouthpieces.com/mouthpieces_101.html |

It's on my Custom C trumpet by the way. I used a couple of other mouthpieces on it without this problem. However, the Kanstul B 1-1/2C with 24bb is the mouthpiece that gives me the sound and resistance I was looking for. So, in short: is a gap adjustment a solution to this problem?

Hi Jeroen!
I think Skip is correct that Bob reeves have these sleeves that fit over to lengthen the gap to your requirements.
However if you are saying that this m/piece is the best you have found for resistance using it in the horn normally, then i would have to say that changing the gap may give you a slightly different impression of resistance.
The thing is you may actually find it improves the performance, it is one of those trial and error things.
I know some folks have tried a small piece of tape around the m/piece and tried it like this simply to get a rough idea of the difference, it will not give you the exact feel of course but it may give you some indication.
My own personal opinion is that maybe you should continue your search for a piece that does the job as it is and unchanged,
Just my thoughts

Thanks for your thoughts Leigh!
I already decided to let it be for the moment. I'm more focussed on the sound (I love that at the moment), then on those two/three notes that are a bit flat. With an audition they listen more to sound then to the pitch of one or two high notes.
Adjusting the gap won't get those couple of high notes in tune, so I've got to find another way. If it keeps bothering me, I'll pay a visit to Hub van Laar, who made my horn.

The Reeves Sleeves really work. I will need to have your m-piece sent off and shaved down before you can use them. I don' t know if they will fix your pitch problems but they will give you a few options to make your trumept play differantly.

The solution I've stumbled on is the following:
I replaced the 24bb with a Warburton 9. High register is almost sharp, so my troubles are over. The Warburton bb also has a better fit in my receiver. Maybe the 8 will still do the same, but with a bit more resistance. I'm going to try that next week. The 9 doesn't give me the same sound (a bit darker and somewhat less focused), but maybe the 8 will be the right one for me. I'll let you know soon.
Thank God for the interchangable backbores! ;D
