Hi, folks.
I love my Privia 5SX--best piano samples on the stage piano market, and nice functionality, but I also am vexed by the key clunking--mine happens on the upstroke and has worsened with time. I use the Privia as my main studio controller and gigging instrument.
MY SOLUTION-- DUCT TAPE THE RESCUE!!!
I developed a little external work-around that has been effective without opening the box. It doesn't affect the down struck, but it does quiet the clunkier upstrokes a lot. It looks a bit funky and it doesn't interfere with playing. I've done about 15 keys and keep adding as they get clunky.
See photos.
STEPS:
- strip a 2 ft. length of white duct tape, width narrower than the width of the white key section between the black keys.
-fold up a 1/3" section about 15 times to create pad
-leave a small tab (about 1/3")
-with needle nose pliers or tweezers, slip the pad between the base of the key (white keys only) and the felt edge of the casing.
-trial and error... if there is still clunking, re-do with more layers. if the key is not rebounding fully, try fewer layers.
- I've had some of these in place for a while and they hold up.
- I've only done this with the white keys... interestingly, the black keys don't seem to clunk like the whites.. I guess the whites are larger with more leverage and compress the felt bushings more.
I also have a 330, which does not have this problem.
Good luck.
