I finally finished it.
here are the specs:
body: hollow chambered Black limba / Imbuya top.
neck: Wenge / Ziricote fretboard, MOP side dots, bone nut, jumbo fretwire, double action truss rod.
hardware: Hipshot supertone bridge (optional strings through body), Hipshot ultralight tuners, Schaller straplocks.
pickups: Nordstrand dual coils.
electronics: series/split/parallel mini-switch for each pickup, active/passive circuit selector switch, passive circuit (volume, balance, tone), ACG active preamp (volume/balance, bass filter stack, treble filter stack)
finish: tru-oil
the sound is deep yet punchy (very deep-rounded bass with low-mid punch), a bit on the dark side ( ) with the passive circuit, but the active preamp can twist the sound to be whatever you want it to be. I think it's nice to have two totally different "vibes" in the same instrument. overall I'm very pleased with how it sounds.
