Hyper Catalyst is a 3-stage class A JFET preamp / overdrive.
It is designed to stack on other drives or overdriven amps and add saturation, harmonics, tighter bass, and more clarity to your tone. Hyper Catalyst will also sound good on its own as an overdrive pedal.
When used as a regular overdrive pedal, Hyper Catalyst is a low gain dirt box that focuses on producing smooth clipping texture. The 3-way headroom switch offers 3 levels of clipping/compression.
High headroom - Clean with some bite, similar to slightly breaking up tube amp and the most dynamic mode of the 3. Single notes stay clean and chords can be clean or clipped depending on strumming velocity.
Medium headroom - Crunchy tone. Similar to a cranked up tube amp. Turning up the "Bias" knob gives you more saturation and sustain.
Low headroom - More clipping, more saturated with a little compression. This mode makes HC work just like any regular overdrive pedal.
- “Focus” controls the treble clarity. Turn counterclockwise to get cleaner tone.
- “Tight” controls the body / fatness,
- “Edge” attenuates the high frequency range and removes fizziness.
- “Bias” controls the overall gain. The more gain the more trebly - use "Focus" to compensate.
- “Output” controls the output volume level
When stacking on another drive or an overdriven amp, “Focus” adjusts the high mid emphasis and the amount of grit, “Tight” tightens up the bass for palm mute chugga-chugga type of tone. “Edge” removes fizziness and makes single notes lead tone smoother. “Headroom” controls the punchiness / compression, “Bias” adjust overall saturation, “Output” pushes the drive/amp after Hyper Catalyst into further saturation.
