Select between all-tube and solid-state input circuits.

You can add real tube overdrive to either clean signal path with an innovative balance control that lets you set the perfect blend of overdriven and clean signals. Lets you maintain clarity and definition while adding grunge or tube warmth. Solid-state output stage for pure, clean power. Variable-contour scoop, bass resonance, and compression controls, plus 5-band EQ with semi-parametric mid supply deep tonal command.

The Variable Contour Scoop sweeps from a flat frequency response through a mid-frequency dip at 400Hz. As you increase beyond the midway point on the control you begin to boost both the top and bottom end of your tone, in addition to further reducing the midrange level.

The Bass Resonance control regulates the damping factor of the output stage, allowing you to take full advantage of the cab's acoustic characteristic with tight, modern sound or looser vintage sound. Quiet, high-quality fans in a dual configuration eliminate the need for heavy heat sinks and keep the amp cool under the most grueling circumstances. The lack of heat sinks keeps its weight down to 25 lbs. Front panel tuner/mute switch lets you tune up quietly and mute the amp during breaks.

Other pro features include highly visible VU metering of the output signal, a front-panel wet/dry control for the footswitchable tube drive, footswitchable effects return with front panel wet/dry blend control, a pre/post selectable XLR balanced DI output with ground lift, and high power-handling Speakon extension speaker cabinet outputs plus 1/4" phono jacks.

Rugged, all-metal chassis and glass epoxy circuit boards mean it's seriously road tough. 2-year unlimited warranty.
