Yamaha CP80B action

[Richard Moody]

If you like the action buy it.  It should be like that for a very long
time.   They are very rugged.  I saw a few broken strings mostly bass
but never any broken action parts.
The hammers appear to be a rubber or plastic core with leather on top.
I can't remember how much the whippen assemply is like the grand
piano. Yes they always seemed "fast" to me.   I tuned them from when
they first came out (78?) untill 1988.  I was never called to regulate
one or repair a broken shank or other parts.   I wondered how long the
hammers would last.  I never voiced one because I was never asked and
it never seemed like it needed voiceing.  I was never called to
regulate one and I never came across one felt like it  needed
regulation.  These were  rock-n-roll and pop performance pianos so
probably had a stage life of two or three years.  I did know some that
went on to 5 and  7  years.
    From the CP series I thought Yamaha might start installing these
parts and hammers in their smaller grands but they never did unless
they started after 1988.
    Their tuning seemed to be more stable probably because there are
only two strings per note and no soundboard.
