Martin, Very ingenious. So much more sophisticated than my connecting Delrin plectrum to my lathe chuck to test longevity. So what was your leather of preference?

Not in an absolute sense, but in the sense that using the device on each key in turn enables one to see whether they all require the same force to sound the note. The imperfect theory behind this is that evenness of touch equals evenness of speech, and that this is a GOOD thing. There are many caveats and simplifications associated with this theory, and I dont use my pluckometer as a final arbiter; but, as a means of getting a more objective assessment of evenness of touch between two notes, I have found it a useful tool.
