AJH Synth is a British boutique synthesiser manufacturer best known for high-end analogue Eurorack modules inspired by classic vintage designs. The company focuses on recreating the sound, behaviour, and feel of legendary analogue circuits, while building them with modern reliability and precision.
Their modules are especially respected for rich oscillators, characterful filters, and authentic analogue signal paths, often drawing influence from early modular and monosynth architectures. AJH gear is aimed at serious modular users who want classic analogue tone inside a Eurorack system, with components and build quality that stand up to professional studio and live use.
For SynthForSale, AJH Synth fits squarely into the premium Eurorack and analogue modular category — specialist modules designed for musicians and sound designers who value vintage character, depth, and craftsmanship over mass-produced or purely digital solutions.

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.

Analogue is sound generation based on physical electronic circuits such as oscillators, filters, and amplifiers rather than digital processing. It is used for its continuously variable signals, natural movement, and harmonic character that respond directly to hands-on control. For example, an analogue instrument might be used to create a warm bass line or an evolving lead sound with subtle changes in tone and texture as it is played.
A filter is a sound-shaping component that removes or emphasises specific frequency ranges. Filters are used to sculpt tone, add movement, and control brightness or depth, playing a central role in shaping raw sound into expressive and musical results.
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.
VCA is a voltage-controlled amplifier used to control the level and dynamics of a sound using control signals. It is used to shape volume over time, apply envelopes, and manage modulation depth within a system. For example, a VCA can be used to control how a note fades in and out or to regulate the strength of a modulation signal across a patch.
