Gibson's Digital Guitar Finally Released
tdiman writes "The world's first digital guitar, using Gibson's MaGIC digital transport standard, was introduced February 20th at the Intel Developers Forum." We've been following this one for awhile, I'm really curious to see what something like this can do.
First of all, since a vibrating string is probably the most simple to understand analog signal, this is basically a guitar with pickups that have an extra set of coils (This isn't the first HEX pickup in the least) to detect string height and an AD convertor or two. Or perhaps twelve. Not too difficult to design, but certainly difficult to implement in a sonically usable manner. Kudos to Gibson if it works well!
Most likely this is the patented pickup:

For one example of a so called "digital" guitar there is of course the Line 6 Variax.

But that wasn't the first to meld guitar and digital conversion.
There are many previous designs, one involving pressure sensitive fretboard sections that would close switches and cause signal processing changes.
Even the Gibson design seen in this post isn't radically different than any past MIDI guitar.
It's all semantics as to what kind of signal you create or whether you performed AD to DA conversion inside or outside the guitar or on each string or the entire signal together or whatever.
Here's a very well done approach to a guitar type instrument that has since been discontinued, but is used by many famous artists. Allan Holdsworth to name one.
