ST-212: 60-watt all-tube 2 x 12" combo with tri-mode rectifier

The B-52 ST-6012 60W Tube 2x12 Guitar Combo Amp with Celestion Vintage 30's has a 100% all-tube signal path that combines Sovtek 6L6 power tubes with 12AX7 preamp tubes for solid tube tone and classic breakup. This B-52 combo amp is capable of monstrous gain, extreme distortion, and sparkling clean tones through 2 channels. All those tones are accurately reproduced by a pair of 12" Celestion Vintage 30s with 70W handling. The Clean and Overdrive channels have their own sets of volume and EQ controls (3-band bass, mid, and treble), with 2 gain knobs and an interactive Contour control (Gain 2) on the Overdrive channel.
