I use a C tuning fork and am going to purchase a F# or G# one.
To me, trying to find a good old upright that someone has sitting around the house is like going car shopping in the back yards of inner city neighborhoods. Some people love that stuff but I want a car that is not mouse infested and known to work sometime in the last week or so.
As to a Stage piano and of the ones you mention, the RD800 is the clear winner to me. The keys of that particular RD in my playing of stage pianos was most like my grand piano. What will beat that, if you can find a deal on one, is a Kawai MP11.
Wrom what I have seen the market of old uprights has really low prices, especially because the market is flloded by newer upright that were leased and "foreclosed" (Maybe the term is not correc). A loto of piano are sold with a leasing contract so one pays like 100 € for four years. At the end of the lease period one could either make the final payment, covering the unpaid capital part or give back the used piano. By the way I could do the same with the RD800, with a shorter lease time, of course.One of the dealer I asked a quote for transport and tuning said that she could give ma a Yamaha U2 five years old for 2800 € delivered and tuned and 2 year warranty on site. And for a lesser known brand proposed one at 1500 €.The RD800 is cool, unfortunately it's a bit pricey. Has great piano sounds but the other sounds are really good. Neveve had the opportunity to tri the MP11, because the Kawai dealer here didn't have one to show. Anyway I still have to see and photograph it. I'll definitively ask a technician to check if it's all ok before moving and see if I have the feeling with it.
Not to butt into your process but why don't you get a relatively inexpensive electronic tuner vs individual forks.
Even better, download the evaluation copy of Tunelab. It measures and adjusts for inharmonicity of your individual piano. I have electronic tuners of course, for band instruments, but they tune to ET (or some other selected temperament) regardless of the scale of your piano, and you don't want that.
Good one Tim, I keep forgetting about tunelab, I guess because I have the tuner and just use that and my ears to hear beats or to hear no beats as needed.
Remember that you need beats and they should be faster as you go up contiguous major thirds.
What temperament do you tune in Tim ?
The Tunelab version of ET (although I see advantages to Bill Bremmer's EVBT3.) Anything but Reverse Well of course!Now I'll tell a story about an intonation incident that happened to me last week. It's off topic of course, but so is anything about tuning.I played alto recorder for the church's Christmas pageant, they always ask for something simple to help one of the children sing along. I practiced a bit and got interested in playing along with some youtube videos. My recorders are Yamaha plastic in various sizes. They are well made but all recorders have some intonation ideosyncrasies (couldn't spell that to save my life) that you just have to ignore. On any scale there are notes that hurt my ears, but they're very close. Well, it turns out youtube videos vary in pitch. One of them was a tiny bit flat to the recorder, so I pulled out the head joint just enough to match it. Disaster. It tuned the F, and threw out every other pitch so that I could no longer tolerate a scale in any key. Why that happens i don't know. I'm going back to trombone which I CAN play in tune. With anything.
How it ended.I've seen the piano. It was in a car garage.Strings were rusted, except some one that were clearly newer. The keys in the middle were wiggly and the felts were a lot grooved in the middle. Was out of tune and some pins on the middle notes were different, some other looked like there was some kind of glue or wax.I suppose that is a "lemon". Am I correct?
