Our new guitar inveniton

Hello group.
This is my first time writing to the list. There seems to be a great
interest in tunings and everthing about them, so I thought I'd let anybody
interested know about our new invention.
Basically, it is a single stringed movables capo system that we install into
guitars. Each string gets a tiny bead which slides up and down the string,
and is held at any fret it is left at. All six beads slide over the nut, so
any combination can be used from zero to all six. This lets the player set
up any chord as a base. Not true down tuning, more like 'uptuning', when
used in combination, the limits are set only by the players imagination.
There are photos and details of our guitar at the super easy to remember
address of www3.sympatico.ca/abacuscapo
Our guitars have only been played by a handful of players, and seeing as
though we are always striving to make it better, we'd love to hear any
comments you may have.
Thank You
