If you play high-gain metal with downtuned or ERG guitars (death metal, prog, djent, hardcore) this thing is perfect for you. I use it on my 8-string guitar and when paired with my Orange 2x 12, I get the tone of my dreams. This is a ported guitar SUBWOOFER that acts as an extension to your normal cab. It reaches those fundamental frequencies that normal guitar cabs (or even FRFR cabs) can't come close to, yet it is voiced to not interfere with the bass guitarist. Though it makes your distorted tone have unbelievable testicular fortitude, I've always been fascinated by the way the sub affects my clean tones. The amount of depth and response I get from this cab is unparalleled. Your tone takes over the room. I am going to miss that a lot but I am looking to downsize my rig. Big names that used Sub Cabs: Steven Carpenter (Deftones) and Mick Thomson (Slipknot) use this exact approach on their rigs. Nick Hexum, Mick Mars, Jim & Mick from Slipknot have them, Head & Munky of KoRn (for a recorded tone, the Follow the Leader and Issues albums used the Bonehead's w/ Sub 2's), Meegs from Coal Chamber (he recorded Dark Days with the Sub 2's and toured with them as well), Adam Jones of Tool used a KS312 sub cab on tour.
