Ran accross this on a newish Steinway B - the tone in the treble was acceptable in the full position and thin-brittle in the shift position. I don't understand why the shift exaggerates the problem... Several technicians before me (including the dealer's) gave up. The hammers were overcentering - nobody caught that... After fixing that it voiced just fine. So I tossed it in the hopper as a possibility - in retrospect maybe I should not have phrased my post quite as authoritatively... (but it was late at night, two days before my wedding so please pardon the sloppy thinking). (Re-reading Everett's post again I'm not sure if his top treble had a "glorious sound" in unshifted position or not...) Israel Stein
