It's a work in progress. It doesn't sound nearly as good as the Starfire. It also doesn't sound as good as the newer TBX Moduli, but I'm not sure why. It's kind of midrange-y, which I thought the Alembic pickups would help, but not so much. It might be because of pickup placement.
Update: I took off the Pyramid flats, put on some DR Sunbeams, bumped up the action a bit and this thing now sounds amazing. I still want to put a real bridge on there, but it really does the job as it is. I'm also waiting for a middle pickup for Alembic.
