A 150-watt, KT88-fueled, High-gain Monster
Boasting a whopping 150 watts of KT88-fueled might and up to seven stages of cascading gain, the Uberschall Mk2 delivers extended lows and highs, plus more raw power, than its EL34-loaded sibling. This dual-channel, high-gain amp head is packed to the brim with versatility, with each channel featuring three different modes to tailor your tone from pristine cleans to cutting crunch all the way to modern metal brutality. Moreover, high-gain fanatics will love how the incredibly heavy Channel 2 also sports a 3-position voicing switch (Doom, Focused, and Bright) and a tightness-shaping Metamorph control for serious sonic control over every aspect of your sound. The power amp offers its own robust set of sound-shaping controls — global Presence, Depth, and Density — and it's all finished off with a 4-button footswitch that gives you hands-free access to the channel select, onboard Gain Boost, second master volume, and FX loop.

Superior sound-sculpting tools
Each channel of the Bogner Uberschall Mk2 comes equipped with its own 3-band EQ, but that's only the beginning of this amp's exceptional tone-shaping power. Both Channel 1 and Channel 2 feature three distinct modes, allowing you to set your preferred gain level, with the highest setting providing up to seven saturated stages of searing gain. In addition, Sweetwater guitarists appreciate how Channel 2's 3-position Voice switch and tightness-shaping Metamorphic control grant you a nearly endless level of raw, crushing sounds to choose from. As if that wasn't enough, the Uberschall Mk2's power amp completes the package with global Presence, Depth, and Density knobs.
4-button footswitch control
Need to take hands-free control of your sound? The Bogner Uberschall Mk2 includes a 4-button footswitch that gives you supreme control with the stomp of a button. While it's no surprise that this footswitch features a channel-select switch, it also gives you access to the amp's Gain Boost (available on both channels) to slam the Uberschall's front end. You can also access the amp's second master volume and the FX loop.
