Catalinbread Epoch Bias

Catalinbread Epoch Bias is a preamp and boost pedal based on a Maestro EP-3 Echoplex preamp with a number of innovative adjustments.

The all-new Epoch Bias expands on a EP-3 circuit with a couple crucial differences. The Bias control simulates out-of-spec parts on the original, adjusting the base gain and body of the EP-3, which adds only a trivial amount of gain on its own. The new Filter control brings you the best of the early and late model EP-3, with a tasteful treble cut that lets you adapt the pedal to your rig and tone. Join us and experience the most refined version of the effect that launched a thousand discographies.

While you are certainly free to place the Bias anywhere you like, it sounds best at the end of the chain as an “always on” to tighten up the entire mix while adding some extra sparkle on top.  A well-curated filter adds a tasteful hi-cut that lets you adapt the pedal to your rig, not the other way around.

The Preamp control lets you engage a gentle filtering circuit that simulates the Volume control from the original Echoplex, acting on the tone as the echo would have. A Boost knob wrings as much gain from the circuit as possible, giving you a real punch where you need it. It’s certainly on of the most tweakable EP-3 offerings to date!
