Description
The Bogner Uberschall Mk2 150-watt Tube Head is a powerhouse designed for the true tone connoisseur. Driven by formidable KT88 power tubes, this amp head delivers a remarkable 150 watts of raw, high-gain energy, making it an ideal companion for those seeking to explore the outer limits of their sound. With its dual-channel configuration, the Uberschall Mk2 offers unparalleled versatility: Channel 1 transitions from crisp cleans to aggressive crunch, while Channel 2 unleashes a torrent of brutal high-gain overdrive, perfect for metal enthusiasts.
Each channel is equipped with a three-band EQ and distinct modes to customize your sound. Channel 2 steps it up a notch with a three-position voicing switch (Doom, Focused, and Bright) and a Metamorph control, allowing for precise tonal sculpting.
