The schematic for the other bass preamp by Alembic, the F2b, can be found quite easily on the net, but I hadn't earlier seen the schematic for the F1x.
The product blurb mentioned something that to me pointed to integrated filter IC's like the UAF42 (although that is reported to sound "not great"), but apparently not :)
