Full Description

Modern J-style tone with active control

The Cort GB-Fusion 4 takes the iconic J-style bass blueprint and enhances it with a fresh sonic edge. At its core is a pair of Voiced Tone VTB-ST single-coil pickups, crafted to deliver a blend of vintage warmth and modern articulation. These pickups capture the rich harmonic character of your playing, from deep fingerstyle grooves to articulate slap lines. Paired with a versatile 3-band active EQ, the GB-Fusion 4 lets you dial in your tone with pinpoint precision. You can shape smooth and rounded lows, snappy mids, or crisp top-end clarity, adapting your sound for any musical scenario. The active electronics open up a wide dynamic range, giving you the flexibility to slot perfectly into any mix.

Premium tonewoods with standout style

Built with a solid alder body, the GB-Fusion 4 maintains the tonal legacy of J-style basses with a naturally warm low end and a punchy, growling midrange. Adding to its striking look is a spalted maple veneer top that brings a burst of colour and texture to the instrument. Finished in a high-gloss Blue Burst, this bass commands attention both visually and sonically. The spalted grain pattern is unique to each model, ensuring that your GB-Fusion 4 stands in a world of its own.

Sleek neck design for enhanced playability

Designed for smooth playability and ergonomic comfort, the GB-Fusion 4 features a hard maple neck with an Indian rosewood fretboard. The satin neck finish gives you a fast, frictionless feel, making it ideal for fluid runs and intricate lines. A familiar C-shaped profile caters to a wide range of hand sizes and techniques, while the 12-inch fretboard radius provides consistent response across the board. The ergonomic neck joint allows for seamless upper fret access, reducing wrist strain and encouraging expressive solo work.

Pro hardware for stability and tone

Equipped with premium-grade hardware, the GB-Fusion 4 offers stability, durability, and tonal clarity. Hipshot Ultralite tuners ensure precise tuning without adding unnecessary weight, which improves overall instrument balance and eliminates neck dive. The MetalCraft M4 bridge enhances sustain and tuning accuracy, with 19mm string spacing offering ideal comfort for fingerstyle players. A PPS nut and medium-jumbo frets boost responsiveness and articulation, supporting both dynamic playing and consistency across the neck. With its black hardware, gloss finish, and pro-level construction, this bass delivers peak quality and reliability.
