The
Yamaha P-120 is a portable
electronic piano. The 88-key keyboard is action-weighted, imitating the feel of a real piano. It includes several sample keyboard sounds, such as
harpsichord,
clavichord,
vibraphone,
guitar and more. Basic sequencing and editing are built-in. Excellent feel to the keys, good tone, easily accessed ports on side (not back). Problems with keys sticking have been reported.
The sticky key problem is caused by the plastic used in the manufacture of the keys for the P120 reacting with the grease used to form an adhesive like substance. This has been recognised by Yamaha. Yamaha will replace the key-bed (part cost only) free of charge if sticky keys are experienced. In 2012 this changed to free part only and the end user pays the labor cost. On December 31, 2013, the replacement keybed program will come to an end and there will be no more free parts offered in the USA.
