[pianotech] Yamaha GA1 Barely 10 years old Has Loose TuningPins- 2nd owner

I’ve found that you can make those cheap Yamaha grands finally get stable if
you ruthlessly control the environment. Dampchaser with cover, and
absolutely no air currents. Seal up all HVAC registers within 20 feet. Check
for ceiling registers as well. And if it is a church have them close the lid
completely between services.

Mike,

 

I haven't had loose tuning pin issues on the GA1, but I can tell you it has
the worst scale and tuning issues I have ever comes across.

 

I tune quite a few of them, but there is one tune for a Church (I can't
believe a dealer would sell this piano to a church), that gets tuned every 3
months. The tenor break is always at least ±15 cents.

 

On the other hand, the Kawai GM-2 (small, inexpensive piano), is one of the
most stable pianos that I tune. Go figure.

I was called to tune this Yamaha GA1 today the lower half of the bass
section tuning pins were very loose, the upper half a little better, lower
tenor barely holding, as I moved up the scale from there it got noticebly
tighter. It appeared to have been CA'd but not too well or whoever did it
started at the treble & ran out by the time he/she got to the bass.

The customer bought it used from a piano "restorer" in Rockford, ILL The
piano hadn't been tuned in about a year & moved about 170 miles to it's
present location. The customer has a dedicated humidity system that keeps
the home humidified to at LEAST 35% today it was 43%, but the piano was
roughly 30 to 55c flat bass being the flattest & a few in the very high
treble being less than 5c flat. 

The customer raised the question, when I told/showed him the loose tuning
pins, if the "restorer" had ever tuned the piano to pitch, I replied it was
a good question to which I had no answer.

Advice?

Comments?

Anyone ever heard of this in a Yamaha or in this model Yamaha?

Any help appreciated, will call Yamaha after the holidays,

 

Mike
