It has a full Alembic Series II setup. I found the pickups and electronics (which were actually just an incomplete bag of parts, so I had to rebuild all that from a schematic) online. The bridge and tailpiece were installed by Alembic. The pickup mounting rings and the door on the back were done here in Boulder by Woodsong Lutherie. Mike Stephens did a great job with the door, including putting the binding on it and shielding it completely in the side with the electronics.
This bass has been through a lot of changes (you can see all the screw holes) including Bartolini triple coils and a Badass bridge, which also sounded really good. With round wounds it even gets a great slap tone! Here it is with an ACG EQ-01 preamp.
