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.

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.
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.
An oscillator is the core sound source in a synthesizer, responsible for generating the raw audio signal that everything else is built from. It produces basic waveforms such as sine, saw, square and triangle, which can then be shaped and processed into more complex sounds.
What makes oscillators so important is their role in defining the character of a sound. Different oscillator types and designs can produce anything from smooth, pure tones to rich, harmonically complex textures. In modular systems, multiple oscillators can be combined, tuned and modulated to create evolving and expressive sounds.
Oscillators are simply great — fundamental, versatile and essential to synthesis. Whether you’re building basic tones or complex soundscapes, they are at the heart of your sound, and you will not be disappointed.
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.
