Description

Edit description

Unleash your inner funk with the Moon JJ-4, a bass guitar that embodies the spirit of groove and innovation. Designed in collaboration with the legendary Larry Graham, this signature model is a testament to the art of slap bass. Crafted in Japan, the JJ-4 combines traditional craftsmanship with modern technology, resulting in a powerful instrument that resonates with depth and clarity.

The Moon JJ-4 is built to deliver a thunderous sound, thanks to its Bartolini 9S pickups and NTBT 2-band active preamp. Whether you're navigating intricate slap lines or laying down a solid groove, the JJ-4's versatility ensures that every note is rich and articulate. The body is made from high-quality ash, providing a solid foundation for a resonant and punchy tone, while the maple neck and fingerboard offer a smooth playing experience.

This bass also features GOTOH hardware, ensuring reliable performance and tuning stability. With its striking design and superior sound quality, the Moon JJ-4 is not just a signature model—it's a statement piece for any serious bassist.
