ST-6012 60-WATT ALL-TUBE LEAD GUITAR COMBO!
Thank you for choosing the B-52 Stealth Series ST-6012 combo.
The B-52 ST-6012 is
a feature-laden all-tube 2 x 12” open-backed combo with 60 relentless watts ripping through
two Celestion Vintage 30s. The ST-6012'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. Switching to Gain 2 provides the
same wide tonal range as Gain 1 but with the addition of a contour control. The contour
control adds or subtracts the all important mids, effectively producing three amazing sounds
that are all footswitch controllable! A 3-position rectifier switch adds even more versatility,
offering Tube AB1, Tube A and Solid-State settings. The ST-6012 also features solid Baltic
birch construction, detachable casters and a three function heavy-duty footswitch.
