Tuning Book

[Avery Todd]

List,

    Does anyone have the name, author, etc. of that tuning book
written by a tech in Canada, I believe, that deals with various
tuning methods of manipulating the hammer, strings and pins?
    Because of a 2-part technical starting next week, I'd like to use
the book some for the 2nd part and need to see about buying it.
    Hope everyone had a good holiday season and is
eagerly anticipating getting back to work. :-) Thanks.

Avery
