Palm keys 20-25 cents sharp

[mcostello]

The palm key notes on my Tru-tone alto are very sharp. If I pull the mouthpiece out, the notes play in tune but the lower notes become ~20 cents fllat. Does anyone else have this issue with Tru-tones? I like the tone of the horn very much-if I can fix this problem, it will be perfect.

I had this problem with my Cannonball alto. It's a pretty simple fix - just put a crescent cork in your D tone hole. I think you can find an article about how to do this on musicmedic.com

Good luck.

you might want to take a look at your key heights for the palm keys.

For another approach that involves inserting a small liner in the neck, check out the post by ToreH here:

Paulwl apparently has posted about this also but I don't have the link for that. Paul, do you have it handy?

My TT alto is tune top to bottom. Never had an issue with it. DAVE

All my t/tones are in tune (alto,tenor and bari). They have superb intonation. Check your key heights.

Would you share your TTs (alto, Tenor and baritone) Key heights with us?

For the two Daves:

What number necks are you guys playing on your TT altos?

[Dave dix]

My true tone alto neck is a number 1. The tone hole gap from bottom of pad to tone hole rim on the widest parts range from 8.5 mm left hand to around 9 mm r/hand stack

My TT alto's neck has no markings on it. The horn dates to early 1920's. DAVE

Dave, thank you very, very, very much!!!

I guess you're talking about your alto. I would like to know in what specific keys do you have that measures. For example: B and F keys or the common left hand key and the common right hand key.

I also would like to know your TT tenor key heights. I've listed my TT tenor key heights in another thread, here I list them again:

Common left stack key: 5.0mm
B key: 5.6mm
Bb key: 6.0mm
A key: 6.3mm
G key: 6.8mm

Common Right Hand stack key: 7.2mm
F key: 8.0mm
E key: 9.0mm
D key: 10.5mm
