Befaco is a Spanish modular synthesiser manufacturer based in Barcelona, best known for Eurorack modules that balance experimental ideas with solid, practical engineering. The company has strong roots in DIY culture, with many of its designs available both as fully built modules and as kits for hands-on builders.
Their modules cover a wide range of functions including oscillators, filters, modulation, sequencing, utilities, and performance tools, often with a playful edge and a focus on interaction. Befaco gear is popular with modular users who enjoy understanding how their systems work and who value flexibility, patchability, and character over polished presets.
For SynthForSale, Befaco fits into the Eurorack and modular synthesis category — versatile instruments and utilities aimed at creative musicians who want expressive, adaptable modular systems with a strong DIY-friendly ethos.

A synth, short for synthesiser, is an electronic instrument used to create and shape sound using oscillators, filters and modulation. Synths can produce everything from classic analogue-style tones to complex, evolving textures used across many styles of music. If you enjoy exploring sound design and creating unique voices rather than simply reproducing traditional instruments, synths offer a deeply creative and expressive way to make music.

Digital is sound generation and processing based on digital signal processing rather than analogue circuitry. It is used for precise control, stable tuning, patch memory, and complex sound design that would be difficult to achieve with purely analogue systems. For example, a digital instrument might be used to create detailed evolving textures or realistic emulations while storing and recalling complete sound setups instantly.
Eurorack is a modular synthesis format with standardised dimensions, power connections, and signal levels. Eurorack systems are built from individual modules mounted in cases, allowing users to create highly customisable instruments tailored to specific sound design and performance needs.
A module is a self-contained unit designed to perform a specific function within a larger system. Modules are commonly used in modular and Eurorack setups, where each unit handles tasks such as sound generation, modulation, filtering, or control, allowing systems to be built and expanded piece by piece.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
A synth is an electronic instrument that creates sound through electronic signal generation and shaping. It is used to produce basses, leads, pads, textures, and effects by controlling oscillators, filters, envelopes, and modulation. Synths are central to electronic music and modern production, offering flexible sound design for both studio work and live performance.
A voice is a single complete sound path within an instrument, typically made up of an oscillator, filter, amplifier, and modulation. It determines how many notes can be played at once and how each note is shaped. For example, an instrument with multiple voices can play chords and layered parts, while each voice handles the sound of one note independently.
