Ric- You will hear a very, very loud beat at 880hz, and an almost inaudible beat at 440hz. Impossible to ignore the 880hz beat. The Seiko gives a harmonic series, so 440hz on the piano will be flat due to inharmonicity of the piano string. Ed /Ric- The Seiko is fine for calibrating electronic devices, but not aural tuning. It has an extremely loud second partial and a very soft first partial./ ------------------- I'm not quite sure I see the problem with that. If you can test beat rates between a reliable pitch source and the note to be tuned with a test interval (or two)... you should be able to get near beatless with the pitch source. That said... as I also said... seems like the Sanderson tool is the thing to get... if a bit more pricey.
