AT-212 100-WATT ALL-TUBE 2x12” COMBO!

THANK YOU FOR CHOOSING THE B-52 PROFESSIONAL AT-212 COMBO! The B-52AT-212 is a feature-ladenall-tube 2 x 12” open-backed combo with 100 relentless watts ripping through two custom-builtB-52 loudspeakers. The AT-212's foundation is outstanding tone, versatility and power. Each channel - Clean and Overdrive - has its own set of gain, treble, mid and bass equalization controls for maximum flexibility.

The Clean Channel goes from classic sparkle to serious crunch while the Overdrive Channel features two independent gain options. Gain 1 moves from bluesy grit all the way to metallic shred. Gain 2 takes over where Gain 1 leaves off for the most intense gain ever.. The assignable contour control “scoops” the all important mids, effectively producing the ultimate metal tone or, when switched out, creates the warm, full bodied tones of the great classic amps. A three position rectifier switch adds even more versatility, offering Tube ClassAB1, Tube Class A and Solid State settings.

The AT-212 also features solid Baltic birch construction,detachable casters and a four function heavy-duty footswitch.
