Sticking Keys and loss of tune in upper registers
by Charles Hollins
(Boston, MA, USA)
I've owned my Yamaha P80 since December 1999. Several keys no longer have a consistant weighted touch, slow reaction time or get stuck.
Also, as I play the upper register above middle C the keys are slightly out of tune with the lower register.
BTW I'm comfortable with electronics and mechanical task.
Notwithstanding, if this is a case for a qualified Yamaha tech I'm all for getting the job done right the first time.
I would greatly appreciate your recommendations.
