    Does anyone have reliable data for initial placement of the duplex bars on the old 57 bass string three bridge A? My data isn't working so well, especially in the note 40 - note 51 range. The chart I have from Steinway doesn't include this Model.

    No, I did not take notes on teardown because it had already been restrung once before and I didn't trust the data. I was thinking I already had it. Figures from the B scale don't work.

    Help!

    This is an victim to try assigning those duplex lengths using Ed Mcmorrow's Fully Tempered Duplex Scale patent. I've used it to figure the lengths and configure the duplex, to, what I feel is, excellent effect...though laying it out does take some time the first few times.
