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 you think? Also just tuned down a Yam C-3 to A=3D415 at Vallotti temperament. I = used my "Quadrant System" to do this, but since I was taking the piano = down in pitch I started of at A=3D411 and went on from there. Finished = in two passes including setting the temperament to Vallotti Over to you! Michael G.(UK) ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
