Detuned or baritone guitars crave this amp. The Uberschall features a high-headroom, classic clean channel with volume, gain, bass, middle, treble and presence controls. Pound all your pedal effects into this channel, and the harder you hit it, the more it smiles to show you its fangs. Unleash the mayhem with the super-aggressive high-gain channel with gain, bass, middle, treble, volume and presence controls. Even with extreme gain and volume, this channel stays massively focused and resists mushing out from the heaviest right-hand attack. Have some crazy effects? Put them through the tube-buffered effects loop. Power comes from a throaty 6L6 output section.
