Sticking keys on a Yamaha CP33

by Mike Christie

Hi, I have used my Yamaha CP33 for about a year and the keys are beginning to become sluggish with the two E keys above and below middle C being sticking down making them unusable during gigs. Is there a fix for this problem. The serial number on the bar code label is EAO J01043

CP 33 Sticking Keys

Dear Mike: The problem could be deterioration of rubber underlay pads (under the keys). I'm not sure which of the following two entities is the correct one, but you should contact them,explain your problem and ask who they can rercommend for service. Thanks for contacting this forum and please come back with questions/ comments any time. Bonne chance!...............

Hi Mike,

You can also try to get a vacuum-cleaner over the keys or with a spray-can compressed air blow possible accumulated dust away.
Failure of the underlay pads is very well possible if you are a 'rough' player but your kboard is quite young and usually they don't let the keys 'stick'.
Take a touch of talcum-powder and blow it in between and if possible under the bandit keys. We had some success with this 'non Yamaha' advice.
