For sale is a Synergy Bogner Überschall dual-channel tube preamp module in excellent working condition. Designed in collaboration with Reinhold Bogner, this module faithfully captures the crushing high-gain tone of the legendary Bogner Überschall amplifier while fitting into the Synergy modular platform.

The blue channel delivers aggressive crunch with outstanding note definition, while the red channel takes things into full modern high-gain territory with massive low end, tight response, and plenty of saturation. Pre-EQ, Boost, and Cut switches provide additional tone shaping, making it easy to dial in everything from hard rock to extreme metal. It excels with drop tunings and extended-range guitars while maintaining excellent clarity and articulation. (⁠synergyamps.com)
