S&S D Duplex

[Duplexdan@aol.com]

Del,

Of all the technicians who contribute to our art I consider you one of the 
finest. yet, until you successfully tune a duplex scale, your comments on 
this feature cannot be considered valid. I did not invent it, and your 
credibilty is not in question but your opinion on this matter is simply 
subject to your knowledge. I have loved and appreciated your classes and your 
contribution to our art, and I am hopefully anticipating your input on this 
matter.
