Where Craft Meets Power.
Step into a new era of bass performance with the HILS ZB, a multi-scale bass built for players who demand more than just low end—a finely tuned instrument designed to inspire.
A mahogany body finished in satin black gives you rich resonance and show-stopping looks. The 5-piece maple/walnut neck with a silky satin finish feels fast and effortless in your hands, while the Indian rosewood fretboard with stainless-steel frets delivers smooth playability and rock-solid durability. This model weighs in at just 7.7lbs (3.5 kg).
Engineered with a multi-scale layout (33.5" to 34.5"), this bass balances tension and tone across every string. The C-shape neck and 12.5" radius make even complex passages flow naturally.
Dial in your voice with a versatile HS pickup configuration featuring HILS Custom Alnico 5 pickups, shaped with active/passive push/pull control, a 3-band EQ and a TriCore switch offering series, split-coil and parallel options. It's outfitted with a Mono-Rail Bridge by Alchemy for perfect intonation and sustain, premium D'Addario EXL165 strings and a deluxe gig bag to take it anywhere.
