I have a 1988 Yamaha U-1. I have a broken bass string, the G an octave and a fourth below Middle C. It's one of the 'dual' strings, (as I'm sure you know). It currently rings out as the damper doesn't have enough juju to keep the sting dampened. Or something.I asked a tech in my area to fix it and they told me I needed a full action refurb. $1500 a few years ago.I would very much like to get the string replaced, but he made it sound like "since I'm removing the action you might as well let me do the whole thing". It sounds like me wanting to replace a tire and the mechanic wanting to take apart my engine.I'm sure he's right, but I have no issues currently with the way my piano plays and I can't believe I can't just spend $100 or something to get a new string without all the rigamarole.Any ideas for what I should say to the next tech I get in to look at it? TIA
