Description

Edit description

The Dreadbox Epsilon is not your typical overdrive effects pedal. This limited-edition unit is a versatile powerhouse, blending a 2-pole resonant filter with an envelope generator for a dynamic range of modulated, filtered tones. Whether you're wielding an electric guitar, bass, or even a synthesizer, Epsilon opens up a world of sonic possibilities.

Designed for adventurous musicians, it offers both lowpass and bandpass filter modes that can be modulated internally by the built-in envelope generator or controlled externally. Its amp section provides both low- and high-gain modes, giving you the freedom to dial in everything from subtle drive to full-bodied fuzz. The envelope section can also loop like an LFO, delivering pulsating, tremolo-like effects. With the capability to handle line-level inputs, the Epsilon can also enhance your keyboards and drum machines, making it an invaluable tool for DJs and producers alike.

Beyond its tonal capabilities, the Epsilon is equipped with four patch points: VCF in, Envelope out, Gate In, and Gate Out, offering seamless integration into your modular setup. The footswitches allow for easy toggling of effects and manual gate triggering, providing hands-on control in live settings. With only 150 units available worldwide, the Dreadbox Epsilon is a rare gem for any enthusiast looking to expand their sonic palette.
