Uberknall Preamp

Based on Bogner Uberschall.

As you may knew from our other Preamp projects Designed by Bajaman we love his circuits, the authenticity of the sound compared to the real amps, the response, the air they moving or the charme the bring depending on the model and well…. this time he deigned one that will smash you to the ground, eat you alive and spit you back out before you maxed out the gain. Actually even I’m surprised, that he did this monstrous metal beast based on the fantastic Bogner Überschall ™ Tube Head. That one is, as far as my knowledge goes, the most brutal amp out there. Believe me, I tried them all. Even the Diezel VH4 ™ was just designed because Peter Diezel was so flashed by this amp that he wanted to build something similar in brutality and sound.

If you’re looking for super heavy metal tones, you are right here. This version comes with only volume and gain knob to give you the most accurate tone you can get. (no worries your amp has a EQ you can use. If you want to use it in the return of your FX loop – we got you covered with passive and active EQ boards as well.) If you are looking for a Rock´n´Roll Drive, pass this one, you will not tame it. We have other Bogner projects on the way, but this one is not in the mood to take prisoners.
