Pitch Raise Experiment K&Cambell

[Don Rose]

Hi Stephen,

I would revise your chart like this

2 cent flat tune
3 to 50 cents flat tune single pass with over pull using an etd.
50 to 1000 cents tune with overpull capped at 5 cents for bass strings and
25 cents for treble strings, then do a second pass with overpull as etd
calculates. Tune again in three months to one week depending on intial
pitch and end results.
