Our "Luke Series" Seismic Audio empty guitar cabinets are made of 1/2" Birch plywood on all 6 sides. These cabinets come loaded with everything you need except the speaker.‚ We are very proud of the Luke series cabinets. These each have a wheat grill of various colors and are covered with a clean cut Tolex. The Luke series cabinets can be front loaded, as the front cloth grill is removable and easily reapplied. Some of the Luke series empty guitar cabinets cab be rear loaded as well (see above). Each cabinet comes with a dual 1/4" metal jack plate and plenty of wire to hook up your speaker. Each cabinet is well braced and offers a nice boutique look. The 2x12C Series is a contemporary look, making it a must have for today's guitar player!
