I bought this several years ago and to my knowledge the seller was the original buyer, and it was in his studio. I have used it only to demo instruments--never gigged. Scarcely a mark on it. It is not being used, so perhaps you can put it to work. Includes the manual as shown--helpful if this is your first venture into biamping. The package includes the head, power cord, the manual...but wait there's more!...I'll include an actual GK Speakon cable, four conductor, 8' length. $365 PayPal CONUS, no trades please. Additional pics available.
