Problem with tuning
« on: April 11, 2010, 09:05:29 AM »
Hello

I tuned my Fender rhodes (Mark I) for the first time yesterday. I didn't have problems exept with three keys : when I pluck one of the tine of these keys, it's like if I could hear two tones, so it's impossible to make a precise tuning.
I wonder which part of the key is dysfunctionning : the tine, the mic ...?

I also tried to find the manufacture year by looking at the serial number, but I can't : 54194

Thanks for your help

The tine can not really produce 2 tones at once, but I think I know what you are talking about.(Most likely overtones) It may be easier to hear the correct tone if you use an  electronic tuner if you cant determine if the notes are sharp or flat by ear. Get them close with the tuner, then put the harp down and play the note. When playing normally, it should be a clearer tone. You also may want to check the tuning springs on those tines, they may be the wrong ones or even loose.

Thank you for your answer. I tried with an electronic tuner (Boss TU-2, I know it's not precise enough but it worked with other keys) but it can't recognise the note ..
So it could come from the springs ? If change them I won't hear the overtones anymore ? Should I find new ones on ebay ?

Thanks a lot

I've had a similar experience; the plucked tine seems to sound a minor second. Someone told me that this was due to a tine being damaged but not yet broken (maybe that's not true, because Steve is generally right on with advice.) I ended up replacing the tine and was OK.

Well a couple of weeks back my lower C# key was producing a tone but with an additional second more audible sound (noticeable when turned off) I thought nothing off it but after a while I decided to unscrew the tine from the tone-bar and re-adjust it. The sound went back to normal so before you start buying parts it's worth giving it a try.

Did you try removing and remounting the tine first?

I forgot about that one...it does sometimes help for sure.

Thanks for the kind words,John. Yes it could also be a tine that is about to break. I was thinking about causes of a couple similar problems I encountered recently which turned out to be spring related.

Yes I tried, it helped me with two tines but not with the third defective one.

Yeah I would agree it's tine related.  Unless it's almost dead from fatigue, it might even be a poor tine from the beginning.  I usually just swap them out.

Jim, I encountered one that had an untunable tine because the springs were too light, adding heavier springs corrected. On another,the tiniest adjustment of the spring made bit either too sharp or too flat-I finally got that one tuned also.
