<HTML>Terry, list, I recently tuned a 1 year old Kawai RX-2 6' grand in a home that was a  half hour drive from my house.  I spent a good amount of time on it because it had gone at least 20-30 cents flat throughout in the year since it had been purchased and tuned.  When I was finished, I was quite pleased with the way it sounded.  Unfortunately, the gentleman who plays the instrument was not there to check it out at the time.  He called the following week to point out that there was little sustain in the mid/lower treble.   I know the dampers were adjusted, and I'd left nothing on the strings to mute them.  The hammers were not grooved at all.  My take on it is that the player had gotten used to a certain sound-- out  of tune--so that when the unisons were tuned, the piano didn't sound the same at all. Anyway, I told him that I'd come out and look at the piano no charge if he could wait until I had another call in his neighborhood(likely very soon--it's in San Jose, CA, a huge metropolitan area with many pianos).  I'd come look at it and correct anything I'd caused or missed for no charge, but if it turned out he'd left a shirt on the strings, or that there was no problem, I'd charge him half a tuning fee for the hour in the car. Sound fair?  Any opinions on this? Dave Stahl</HTML>
