I just recently purchased this and traded in my Peavey Triple XXX straight cab. The Genz Benz is awesome! It has more crunch than any other cab I have used in the last 12 years. Definitely need to boost the mids and highs on your amp more for this amp because of how much low end it puts out. I use a Schecter Scorpion Baritone w/ a DiMarzio Super Distortion and a ESP H-1000 Deluxe w/ a Seymour Duncan JB through a Krank Revolution head. I have finally found the tone I was looking for! I play alot of Fear Factory and classic metal in my band along with heavy originals. This cab sounds great with the Krank Revolution having a 8 ohm mono out. The wheels on the bottom of the cab suck big time however. I just took them off an put it on an amp isolation block. Fantastic!

Handles a Peavey Triple X head no problem this cabinet needs more power maybe an extra 1oo watt slave would really show the potential of this cabinet it rumbles and really pushes the high end also the marshal 350 watt was the only cab even close to the rumble I wanted ,a great cabinet period.
