Moog Guitar:

Ok, seriously now.

How does it work?



My thinking is some sort of electromagnetic resonance going on between
an ebow-style coil and the strings which are probably under voltage.
The resonant feedback would work like this:
string vibrates accoustically -> pickup creates signal -> ebow-style
inducer creates alternating magnetic field (AMF) to add power to the
string's vibration

then, of course, the pickup creates a stronger signal and so on and so
forth. Some power limiting between the pickup and ebow through simple
compression.

Thus, you get infinite sustain.

This happens for each string separately: so good single-string pickups
are important.

The strings are supposedly made out of 'special metal'. This is
probably some sort of steel that has better electromagnetic
properties. I'm shit with electromagnetics - so I will only assume
that it's something odd like magnetic capacity or flux transformation
or gizmodic doohickeyness, that normal nickel-vanadium strings don't
have or have too much of.

There's also the point of damping out 'unused' notes. I guess it's a
question of detecting the strings touching the frets, and if not,
inverting the signal going to the inducer.

Yes, I realize inducer might not be the best word here.

How about we make one? :)

And fretless at that? :) And with comb filters in the feedback stage? :)

And since we're having multiple pickups, a multiple-out into a GK2 is a must ;)

Cheerio!
