Here's my newly completed Bluesmaster 50. Nik built the chassis, I built the cabinets. The blank rack space is for loop effects, probably a G-major 2, haven't yet decided. Plenty of room to change tubes, or even a third rack if I modified the front. Tolex is wine taurus, fender wheat grille, 2 x G12-65s. The racks down the bottom are convenient, but do make the proportions look a little odd IMO.
