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 produces continuously variable signals with natural drift, saturation, and harmonic character, giving sounds a distinctive warmth and movement. Analogue instruments are valued for their hands-on control, immediacy, and expressive response in both studio and live performance environments.
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.
Polyphonic is the ability to play multiple notes at the same time. Polyphonic instruments allow chords, layered harmonies, and complex musical passages, making them suitable for pads, harmonic textures, and expressive performance.
Synth for Sale has over 1000 used synths and gear like that for sale. We bring these products to you via our trusted partners, retailers and direct with independent sellers in the UK.
Wavetable is a method of sound generation that uses a collection of digital waveforms stored in tables. It is used to create evolving and complex tones by smoothly scanning or switching between different wave shapes. For example, wavetable synthesis can be used to produce moving pads, shifting basses, or textured leads that change character over time.
