[CAUT] M&H "A" stability

[David Love]

Is this one of those that has a singles on every third unison through the
tenor and treble?

All,

 

We have a 1992 Mason and Hamlin A that has had tuning stability problems for
at least the last 8 years (since I've been here). It has been assigned to
several solid tuners with the same outcome, so it's not that. It has been
restrung twice, and the last time I put in a new Nossaman pinblock and made
sure that it was installed properly, mated to the flange, horn wedge is in
place, yaddah, yaddah.

 

The last restringing was 2 years ago, and I still need to tune it about
every 3 weeks. The pitch doesn't go up and down, but individual notes just
seem to go wild. I can't say that it is the same notes all the time, I don't
think it is. All the normal prepping has been done, checked and rechecked.

 

Since it was fairly expensive to buy, and since it was a M&H I thought it
should be in a classroom where they do masterclasses. After fighting it for
nearly a year I put it in a practice room. Even worse results. Now it sits
on its side in storage.

 

Any thoughts here? I've been told that the tension resonator should not be
messed with, but could this be an issue? What am I missing here?

 

Thanks in advance.
