Boss Intros EURUS GS-1 Guitar Synthesizer

At the 2021 Summer NAMM Show, BOSS has introduced the EURUS GS-1, a guitar with an onboard synth engine.

BOSS says that the EURUS GS-1 infuses a premium instrument with advanced guitar synthesis techniques, refined over more than four decades. The instrument has the sound, feel, and detail you’d expect from a pro-quality guitar, paired with a polyphonic BOSS synth engine.
