Tech 21 Landmark 300 Amp. I bought this from a dealer NOS. I never used it. Got it as a backup for my SVT. It has been sitting in my closet since I got it. In original box, with manual. Also comes with foot-switch. ( a $110.00 extra. ) And power cord. I've seen these sell for $550.00. without the foot-switch. Again new in box, no issues. $525.00. Shipped. Only trade interest is a 2x10 or 2x12 combo . Worth same $525.00 value.
