And the winner for the coolest-looking synth of 2026 goes to Edgehog EH-01.

It has a multimode sound generator, synth engine, drum machine, sample playback, and the cyberpunkiest styling this side of Kaneda's bike. Quote: gearnews.com

Powerful Hardware

At the heart of the instrument is a Teensy 4.1, a high-speed 32-bit ARM Cortex-M7 processor running at hundreds of megahertz, paired with a dedicated stereo audio codec for true 44.1 kHz digital audio output.

About Edgehog Systems

Designed, built and tested by hand.

Hi, my name is Leo Rolph. I am a designer working from a small home studio in Fremantle, Western Australia. With a strong background in graphic and product design, I have always had a small obsession with electronics, synths and sound generation.

EH-01 is the result of multiple years of experimentation, many synth prototypes and a long string of design choices. It did not start as a commercial product. It started as an instrument I wanted for myself: small, capable, non-standard, immediate and built around several different sound systems I could use for my own sound generation.

The final EH-01 is an attempt to give other people the same kind of hands-on joy I get from playing with it.

Two quick looks at EH-01 in motion: hands-on controls, sample behaviour and the rough edges that make it feel alive.
