Bogner Uberschall Overdrive Pedal


The Bogner Uberschall is an iconic high gain amplifier that has found its way in to some of the best rigs in the world. The amplifier is also known as 'Armageddon in a box' and that title could easily be spread to this pedal as well which brings that powerful tone to the floor.


This pedal feels like real high gain amp distortion. If for no other reason than it is built with five discrete class A gain stages rather than using diode clipping. This brings across the controls and response you would expect from a real amp including the ability to clean up nicely with your guitars volume control.

If you love high gain and want to completely transform your clean amp to something new this is worth checking out. Even at lower gain settings this thing screams like the hard rock machine it was designed to be. From 1 to 5 on the gain control you are in perfect classic rock terriroty, past that you enter the world of modern high gain.

One Channel to Three

Like the Ecstacy pedals the Uberschall has both a built in overdrive pedal and a boost section as well. This makes it incredibly easy to change your single channel clean beast in to a 3 channel rock and metal machine. Just set up the main distortion to fit your rhythm tone and introduce the boost function to kick your leads into sustain heaven.

Response and Control

Even though this pedal is made for high gain power it still cleans up wonderfully. Thanks to that amp preamp like design you can dial your guitars volume back for all of the crunch tones you would ever need. This works incredibly well with something like a strat where the single coils have that stunning midrange honk.

Here's what Bogner say about the Ubershcall Overdrive Pedal

In 2001 Bogner launched the Uberschall amplifier. More than a decade later, Bogner still hand builds each one, right here in Los Angeles, California. Dubbed "Armageddon in a Box", the ferocious Uberschall pedal derives its thunderous hi-gain tones from the notoriously brutal Bogner Uberschall amplifier. While the Uberschall pedal offers a significant range of classic lower and medium gains, its true nature comes forth when deliver­ing savage, face-melting, high-gain aggression - don't say we didn't warn you!

Reinhold designed the Uberschall pedal with five discrete Class A gain stage without diode clipping, mirroring circuitry of the Uberschall amplifier's high-gain channel. This revolutionary approach provides clarity, touch sensitivity and note separation never before achieved in distortion pedals.

The Uberschall pedal is powered by a standard 9V battery or 9VDC power supply.  Reinhold's advanced circuitry internally elevates the voltage a substantially higher level.  This higher voltage provides a greater dynamic range which closely resembles the feel of the Uberschall amplifier's legendary tube design.
