Cool!
Ja its a crazy thing, used on open E for slide with pedal 1 taking the high B to c#, pedal 2 taking the g# to A, and pedal 3 the low B to C#.
The whole thing takes it to anA chord from the E, A C#m if you only use 1 and 3, or a sus4 chord if you only use number 2 pedal.

I've got one of these on a strat, which allows me to go from standard to open E or open G at a flick of a few levers.
Slide solos on the fly!
Blows all the guitarists minds when they hear it the first time! ?
Gotta love the music!
