Loose Keys - wobbly Keys
« on: November 19, 2018, 04:54:00 AM »
Hi guys,

the keys on my Fender Rhodes 88 MarkI are very loose and wobbly (I'm no english-native-speaker but I hope I can make myself clear). I looked all over the internet for a solution to kind of "tighten them up". Maybe I use the wrong keywords for my search. So I really hope I can find help on this forum.

When I press any key the key won't return to its original position without wiggeling/wobbeling a few times. Here's a youtube-Link of a clip I made showing the problem:

Does anybody have any advice how I can solve this problem?

Thank you very much in advance,
Shoebird.

Key bounce is a shortcoming of the Rhodes piano simplified action.  Some pianos have it worse than others.  My 1983 plastic-key Rhodes bounces as bad as shown in your video.

Backchecks are the most complete solution.  I haven't ever seen a Rhodes with backchecks installed.

See https://www.youtube.com/watch?v=LKKST7SqGoM


I have always wanted to experiment with some sort of impact-deadening material under the back of the keys.  Like some sort of solid gel or asphalt under the felt strip (see part 37 in http://www.fenderrhodes.com/org/manual/fig2-1.gif).  Maybe a thicker or looser strip of felt might help.  Maybe just a routed slot of dead air under the felt could work.  But this is a lot of work, and I don't want to do any destructive testing on my Rhodes pianos, even the plastic-key unit.

Keyweights at the back of the keys might lessen the bounce, but I have no idea how bad they would affect the feel of the action, and it would be a science experiment to figure out if they would work in this case.

Of course, neither of these two solutions would completely stop the hammers from bouncing like they do.

Yeah, so, your best options are learn to live with it, or install backchecks.

You might want to buy the full Vintage Vibe restore video (it's $5.) They recommend extra screws in the balance rail for bouncy keys with aftertouch. They have other recommendations for hammer bounce which may help your key bounce.

Thank you guys,

one day and already two very useful tips. Thanks for the video-link! I'm not sure about the backchecks. I would prefer to replace an original part instead of adding something that's not original. But I will think about - thanks for the advice, sean!

Great Forum!
