Uberknall + Amp Tone Stack

Project overview

Inspired by Bogner Überschall a legend in the world of high-end, high-gain guitar amplification. It’s ability to pile on all-tube distortion while letting every string ring out has made it a go-to amp for an incredible range of players.

Introduction

As you may know 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 are moving, or the charm
they bring depending on the model and well…. this time he designed one that will smash you to the ground, eat you alive and spit you back out before maxing out the gain.
Actually, even I’m surprised that he did this monstrous metal beast based on the fantastic Bogner Überschall ™ Tube Head. As far as my knowledge goes, that one is 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 in the right place. This version comes with an Amp Tone Stack section that adds Treble, Bass, Midrange, and Presence in addition to the Volume and Gain knobs of present in our Uberknall Preamp. Click here for more information.
