You bring up an idea that I have thought of before, but never
mentioned: Remember the Flatt & Scruggs style of playing when they
would slide up and down the scale by changing the tuning peg? Well,
with the Lever adjustment, you have the same capability. At the next
SNAG conference (and or Orchid get together) the musicians of the
crowd could get together, and if they had amps, could do a song.
Just to make it interesting, I would donate a 3" fret saw. It should
be a fun event! Lee (the saw guy)
