High-Quality Guitar Designed for the Sonically Adventurous!

The Eurus GS-1 fully leverages Boss’s vast expertise in guitar technology to bring endless creative possibilities to your music. This inspiring instrument has all the sound, feel and detail you’d expect from a pro-level guitar, coupled with a polyphonic Boss synth engine that offers a stunning range of analogue-flavoured sounds to launch your musical expression into a new dimension.

With onboard Bluetooth too, you can customise synth sounds and control multiple performance parameters with the convenience of wireless connectivity. This machine is perfectly-suited for the modern musician!

Electrifying Synth Technology

The synth engine in the Eurus GS-1 delivers exceptional sonic quality and natural touch response realised through 40-plus years of Boss guitar synth development. The six onboard memories come filled with ready-to-play sounds, and you have access to many, many more via the GS-1 Editor.

There’s also a synth control knob that enables a wide range of dynamic expression as you play. Every synth sound offers smooth playability that fully responds to all your guitar techniques, with no latency or triggering issues to disturb your musical flow!

A Plethora of Custom Sounds via Bluetooth

The GS-1 Editor app for iOS and Android mobile devices unlocks deep programming power for the Eurus GS-1's synth engine. Many different synth types and variations are available for crafting sounds, along with tone, resonance and other adjustable parameters.

You can also assign a range of target parameters to the guitar’s synth control knob and save favourite sound combinations on your device for quick loading before performances.

Wireless Performance Control

The optional EV-1-WL Wireless MIDI Expression Pedal brings cable-free external control to the Eurus GS-1 via Bluetooth. Using the GS-1 Editor, you can assign parameters such as pitch bend, hold, filter depth and more to the EV-1-WL’s pedal, toe switch and up to two external footswitches.

Each sound can contain its own set of assignments, allowing you to perform octave bends on a synth lead, slow filter sweeps on a pad sound and nearly anything else you can dream up!

Professional Features for Serious Players

Crafted in Japan with pro-quality details and components, the Boss Eurus GS-1 is simply a dream to play. The modern offset body design is stylish and well-balanced, while the slim-profile neck features a compound radius fretboard for extra comfort and 24 medium jumbo frets for an extended range.

High-performance Gotoh hardware delivers smooth tremolo action and solid tuning stability with a two-point fulcrum bridge and staggered-height locking machine heads. Custom-designed for the Eurus GS-1, the two humbucking pickups provide wide-range tone plus split-coil voicing at two stops of the five-way switch.

Seamless Expression

The guitar and synth electronics are fully independent in the Eurus GS-1, allowing you to switch between the two voices seamlessly. Use it as a regular guitar, then instantly transition to the selected synth sound with the flip of a switch. And with the two ¼-inch outputs, you can send the guitar and synth to separate destinations for dedicated processing.
