The Silicon Zuppa El Coco is an analog distortion preamp pedal. The maker bills it as "El Coco - Dual Rectifier In A Box", a shorthand for a pedal built to deliver the kind of high-gain distortion associated with a dual-rectifier style amp from a stompbox1. As a preamp as well as a distortion, it is designed to shape gain and level in one unit, placing it alongside other preamp pedals as well as conventional distortion pedals2.
What it does
The El Coco takes a guitar signal and adds distortion in the preamp stage, in the manner of a high-gain amp's front end. Because it is a distortion preamp rather than a straight distortion, it is intended to function as a gain and voicing stage in its own right, whether into a clean amp, a power amp, or the front of a pedalboard2.
The circuit is analog1, which matters to players who prefer analog gain stages for how they respond to picking dynamics and guitar volume changes. RockBoard's PedalPedia lists the pedal on its PedalPedia page under the "DISTORTION" category, and the same listing identifies the maker as Silicon Zuppa1.
Questions
What is the Silicon Zuppa El Coco?
The El Coco is an analog distortion preamp pedal made by Silicon Zuppa. The maker describes it as a Dual Rectifier in a box, meaning it aims to put the character of a high-gain amp-style distortion into a pedal that can drive an amp or a clean signal chain directly.
Is the El Coco analog or digital?
The El Coco is an analog pedal. Its circuit type is listed as analog on the maker's product page, so it processes the guitar signal with analog circuitry rather than digital modeling.
