Doesn't stay in tune. This is not one I tune for = there are two of us and this is a rehearsal stage piano. My colleague asked me = to have a go at it while he stood by. It seems it was tuned just yesterday and = already the top two breaks were in trouble and the effect was creeping down into = the middle break - unisons weren't unison. Yuk! So I inspected it and = found there is quite a lot of Joe G's "flag-poling" going on. Of course you = recognise the model (it also has MII stencilled on the web beside the CA-40). My = gut feeling is there is too much "give" in those wrest-pin bushings. I was = just wondering whether a good old dose of CA might not be in order...it might = just harden those bushings...What do <EM>you</EM> think?</FONT></DIV> <DIV><FONT face=Arial size=2>Also just tuned down a Yam C-3 to = A=415 at Vallotti temperament. I used my "Quadrant System" to do this, but since I was = taking the piano <EM>down</EM> in pitch I started of at A=411 and went on from = there. Finished in two passes including setting the temperament to Vallotti</FONT></DIV> <DIV><FONT face=Arial size=2>Over to you!</FONT></DIV> <DIV><FONT face=Arial size=2>Michael = G.(UK)</FONT></DIV></BODY></HTML>
