Preamps, Modifications & Upgrades / Re: Adjusting touchweight

And I've never heard of anyone measuring down weight only with the sustain pedal pressed.
It will always be lighter with the pedal down. Most people I know want to know the measurement with the dampers in play too. But again, it doesn't hurt to measure both ways and compare the difference... Maybe it's just the way my PTG chapter teaches how to do this.
I don't remember learning this anywhere else.
I was just always under the impression that not pressing the pedal gives the "true" reading.

Here's a detail loaded piece on this subject.

Thanks Peter. I think I skimmed that one as part of my research.

"Lead weights will indeed counterbalance a heavy hammer, but will also add inertia: actions with a large quantity of lead in the keys feel sluggish, especially when trying to play fast repeated notes, trills or in any other situation where the key has to move quickly."

This may be where I'm headed. We'll see. I've got another late 70s here (albeit with bump-modded flat pedestals) so I should be able to do A/B testing. If I can't tell immediately, I may try to find some local pianists to provide an opinion.

As it turns out, lots of lead in the keys is more of a symptom than a problem.  The lead is needed when the action ratio or hammer mass to too large.  That's what really causes the sluggishness.

Why would you only measure down weight with the pedal depressed? I've never heard of that and it's been discussed at PTG meetings. We were always shown measuring with gram weights but nobody ever said to depress the pedal. That would make it lighter than it actually is. Maybe comparing with the pedal pressed and not pressed would be a good thing to do, but we've never been taught to do it with just the pedal down.

I've never heard of anyone measuring touch weight without the sustain pedal depressed, and the link from Peter Hayes confirms my belief.  Releasing the sustain pedal and measuring touch weight will certainly reveal how much extra force the damper action is adding, but it won't tell you how much of that force is due to spring force and how much is due to the weight of the damper arm and damper.

That looks really amazing, allthough I'd rather keep them original. Those guys at CEP really know what they're doing :)

Have fun with it!

That looks fantastic. I just love the cheek blocks.

I have a rule with my wife. Any keyboards, amps, etc. have to fit into my music room. No spillover allowed. So I sacrificed a closet and put in an industrial set of shelves that I use to store my digital keyboards that are used for gigs and some of the vintage ones as well so I do not look like a hoarder. I rotate them in and out so all get played depending on what I am into.

That being said, she really loved the look of the wurlitzer 145 I fixed up so it is "allowed" in our bedroom. The grand piano is also excluded from the rule.  ;)

Last December I decided I wanted a Rhodes, so I contacted Chicago Electric Piano Co. ... who had done my "mellow yellow" custom paint job and refurbishment on a Wurlitzer EP ...  and requested a quote and some customisation.

Not withstanding that it was completed in the middle of February, but I only just received a couple of days back, here is a fantastic 1973 Fender Rhodes "Stage 73" electric piano. Sounding as great as the refurbishment and restoration looks.

I now have two issues... where to store the lid !   :D
How do I re-arrange the 7 keyboards I have so I do not look like some weird arsed old woman who has 47 cats and piles of newspapers going back 30 years.  :-[

Currently prototyping a preamp for it


Here is a clip that REVERB did of my Rhodes before it was shipped.

Look for 8 digit numbers on the wood when you next open it up.  There should be an upside-down one on the back right, behind the dampers, above a number like "A-60-5”. That and any numbers on the keys will give us the best idea of the assembly date.

Great pix!  Thank you!
