I'm working on a full writeup for the Fennario website, but here are the nitty-gritty details for now:
Warmoth Neck - Maple and Purpleheart lamintes with a Ziricote fretboard.
Warwick Bridge and Nut
Bartolini's original series pickups (passive humbuckers)
ACG preamp - with high and low pass filters, somewhat Alembic-like
Custom body made of Maple and Purpleheart with a Mahogany core, and Coco Bolo top and back.
So far I'm really happy with the sound... it's pretty close to Phil's first full Alembic prototype, Mission Control. The ACG really does a good job of copying the way his sound changed from show to show in the late 70s. And yep, it weighs a freaking ton... about 13.5 pounds.
