I finished my little BluesBird emando last fall built from components from Moongazer Music (pickup, neck, bridge).
Wonderful little instrument and exactly how I hoped it would turn out when I designed it.
On a negative note, I've never gotten much adjustment at all out of the tone knob, and the volume knob only works at the very last 30 degrees or so of rotation.
The pickup is an Almuse MG4, and its wired for coil tapping. I do get nice varied sounds from each of the 3 positions on the switch- 1st position gritty and complex, 2nd position clean with very little edge, 3rd position same as first but with a little more bass and less treble (pretty slight differences though betwee 1 and 3).
Tom Morici at Moongazer provided this wiring diagram and I wired it to the diagram as far as I can tell.
I realize this is pretty hard to interpret, but this is the back of the pickguard and the wiring I did.
If I remember right, when I wired up the mando, I did verify that one of the pots was a volume pot, and the other a tone pot.
