This unit is two feet square by four feet long, and half of the interior is occupied by a ported 1 x 12" speaker cabinet loaded with a Celestion Vintage 30. The cabinet is acoustically isolated from the exterior cabinet, which is sealed and soundproofed. It has gooseneck stands and inputs for up to three microphones.

Crank your Marshall up to ten and stand right next to this...you'll hear the speaker working, but just barely. Nice for getting good dry guitar sounds. With the three mics ins you can independantly mike the cone, bass port, and ambient...or whatever strikes your fancy.
