A 100-watt, 6L6-fueled, High-gain Monster

Boasting a whopping 100 watts of 6L6-fueled might and up to seven stages of cascading gain, the Uberschall Mk2 delivers a cleaner sound, with less distortion than its KT88- and EL34-loaded siblings. 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.

Reviews

The Holy Grail
No other amplifier in my experience is as versatile or tweakable. You can loosen the bottom end, or make it as tight as you like. The 3 "Hair" presence settings completely change the character of the amp, so that you can make it fit into any genre - and all of it is usable!

Do I wish it had more channels? Sure, because it would reduce the number of settings I need to memorize. But this is a small gripe, hardly worth mentioning. It's also a very quiet amp. When it hisses, it means you might want to consider turning down the gain - of which it has more than you will ever need!

It's the Überschall that we've all been begging for. And no boost required! Just pure Bogner tone.
The most incredible high gain amp
I've had a lot of amps from Fortin to MI Audio, Original Uberschall, VHT, Peavey and more. This amp is absolutely the most punishing amp I've ever owned. Everyone has their preferences but this is the one for me.
Unreal
First off, this amp does all of the hi-gain heavy sounds you're imagining it would do and then some. The toggle switches can cycle through so many different sounds to get you whatever tone you are looking for or havent even thought of. The biggest surprises on this amp come from the first channel. The clean channel will make you laugh because its so unexpectedly great. The crunch tones that can be dialed in align with some amazing AC tones and you can dial in a great hi-gain rhythm tone as well. The only very small knock you could give it is it probably needs some midi capabilities to better utilize all of the achievable sounds this amp can accomplish. The sounds, quality and exclusivity, not to mention the price point compared to other boutique amps within the category make this amp perfect.
