The 3-way toggle switch is fundamental/2nd harmonic/upper harmonics.
Fundamental is more ebow like, sustaining the actual note. The upper
harmonics position is more Jimi-in-front-of-cranked-Marshall.

I've never gotten around to checking out the circuit in mine, but I suspect
it is pretty simple. They just take the signal from the bridge pickup,
filter it, and use it to drive the neck pickup in reverse. Just as strings
moving in the pickup's magnetic field produces an ac voltage at the output
of the coil, applying a signal voltage to the coil output will cause the
motion of the magnetic field to move the string. NotRocketScience (tm). You
need to make sure you get the pickup placement right so that you drive the
string in phase.
