Project overview

Based on the frequency response of the Bogner Uberschall. Part of the series ‘Develop your own Preamp’ where you can combine preamp sections of iconic amplifiers with different types of eqs in order to create your own custom boutique pedal. More information about the EQ sections here.

When making this pedal, you can choose between the standard version of the High-Gain Mode.

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 moving or the charme the 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 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 an 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.) We even dared to add a High Gain MODE option that gives you even more destructive power. Choose it if you have nothing to lose and everything to GAIN!

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.

Controls

  • Gain
  • Level
  • Send & return pads to attach an external EQ
