Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Catalinbread Epoch Bias is a variant of the Epoch preamp series based on the Echoplex EP-3 tape echo unit preamp circuit. The original EP-3 Echoplex had a Bias control that affected the preamp character when adjusted, and the Epoch Bias translates this specific tonal variation into pedal format. Delivers the warm, vintage Echoplex preamp coloration and boost that made the EP-3 unit influential in studio recording and classic rock guitar tones. Built by Catalinbread in Portland, Oregon.
The Catalinbread Epoch Boost is a preamp and buffer pedal that employs the same circuitry as the Echoplex EP-3 tape echo unit preamp stage, using NOS Orange Drop capacitors to accurately capture its warm, slightly colored tone. The Boost control delivers the EP-3 tonal character when rolled off, plus up to 20dB of crystal-clear boost as the knob increases. Internally upscaled from 9V to 22V for authentic headroom. True bypass switching plus a switchable buffer mode for long cable runs. Power draw only 2mA at 9V DC.
