Bogner Uberschall Mk2 100-Watt Tube Head – EL34 Version New | Pre-Order (ETA: 2/20/2026)

Uberschall is the German word for “supersonic” and we designed this amp primarily for extreme, heavy and aggressive styles of music. Detuned or baritone guitars crave this amp.

The Uberschall Mk2 features a high-headroom, classic clean channel with volume, gain, bass, middle, treble and presence controls. Pound all your pedal effects into this channel, the harder you hit it, the more it smiles and shows its fangs. Seems pretty innocent huh? Just wait… we then unleash mayhem with the super aggressive high gain channel. You think you’ve heard BASS before, no way – the Uberschall Mk2 can crush on demand. 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 EL34 output section.
