Description
The Prehistoric Dog high-voltage Preamp Distortion Pedal by Berserker Electronics
The Berserker Electronics Prehistoric Dog is a high-voltage preamp distortion pedal that faithfully recreates the iconic Sunn Beta Lead and Beta Bass circuits in a compact, pedalboard-friendly format. Rather than offering subtle coloration, it delivers a raw, aggressive tone characterized by tight low end, cutting mids, and a gritty, fizzy top. Thanks to its internal charge pump, it runs at proper rail voltage, giving it the same headroom and punch as the original amplifiers. Designed as a true preamp, it can be used in front of a clean amp, into a power amp, or even directly into an audio interface. Its versatile voicing makes it suitable for guitar, bass, and extended-range instruments alike. Overall, it’s built for players seeking that unmistakable solid-state roar associated with bands like YOB and Red Fang.
Specs:
• Clone of Sunn Beta Lead and Beta Bass preamp circuits
• High-voltage internal charge pump for increased headroom
• Functions as a full preamp, not just a distortion pedal
• Compatible with guitar, bass, baritone, and other instruments
• Flexible EQ shaping based on original Beta voicing
• Pedalboard-friendly enclosure design
• Suitable for use with amps, power amps, or direct recording setups
• Aggressive solid-state distortion character with tight lows and cutting mids
