Hi all,

We have several Yamaha U-3's here at the School of Music.

I find that they, above all the other uprights, tend to go quite sharp in the middle section and flat in the bass.

Has anyone else noticed that?

Thanks

Paul

There are no DC's installed on any of our uprights.

I'm wondering why it happens so dramatically on just the U-3's?  The other Yamahas are pretty stable and the grands are also good.

Is there a design issue with the U-3's?

Roger Gable, do you have an idea?  I know you have a bunch of them in your rental fleet.

When tuned, they are great. Nice and clean with very little false beats or other upright issues.

These are also about 25 years old. They all have the 3 pedals with practice felt bars.

Are there other ways to know if they are "gray".

Yes, your areas are the same. Massively sharp about A46 to the tenor break and then flat in the bass.

No other uprights do this:  Hamiltons, U-1's, all about 20-40 years old.

Thanks
