A Maestro Echoplex-inspired preamp!
The Maestro EP-3 Echoplex has been responsible for some of the most iconic tones in rock history.
In 2020, Catalinbread delivered a pared-down version of this classic with the Epoch Boost.
The all-new Epoch Bias expands on the circuit with extra variables that let you craft your perfect EP-3 experience.
Catalinbread added a Bias control, which gives you a little more gain and body by simulating out-of-spec parts in the preamp core.
The new Filter control brings you the best of the early and late EP-3, with a tasteful treble cut that perfectly adapts the pedal to your rig.
The stock EP-3 adds only a trivial amount of gain, so Catalinbread included a Boost knob to wring as much gain from it as possible.
Plug into the Epoch Bias and experience the most refined version of the effect that launched a thousand discographies!
