If a traditional double bass and a modern electric bass had a brilliant, boundary-pushing baby, it would be the Ibanez UB804.
Born from the Ibanez Bass Workshop, this upright electric bass reimagines what it means to hold down the low end. It blends the woody, breathing resonance of a classic acoustic upright with the fast, familiar feel of your favorite four-string. You get the glorious thump and swell of an upright without wrestling a massive wooden behemoth into the back of your car. It’s a sonic sandbox for bassists hungry to explore new musical territory.
Shift Your Sound Seamlessly
Transitioning from a standard electric bass to an upright usually requires a learning curve the size of a mountain. The UB804 totally flattens that peak. By utilizing a familiar 34-inch scale length, your hard-earned muscle memory translates instantly, making the jump from strapped-on electric to standing upright feel completely natural.
34” Scale Length: Mimics the exact fret spacing of a standard electric bass, eliminating the daunting stretch of a traditional upright so you can play in tune immediately.
Conical Compound Fingerboard Radius: This expertly crafted radius allows for both furious fingerstyle plucking and smooth bowing, giving you complete right-hand freedom.
5pc Maple/Walnut Neck: Delivers rock-solid stability, superior attack, and bell-like tonal clarity that cuts right through the densest mix.
Big Upright Tone, Bite-Sized Body
Hauling a traditional double bass to a gig is like carrying a piece of antique furniture up a flight of stairs. The UB804 offers a brilliantly compact Maple wing body that balances form and function, delivering that coveted acoustic airiness without the chiropractic nightmares. It projects a robust, natural sound that belies its slim silhouette.
Maple Wing Body: Offers a bright, clear, and highly articulate acoustic tone while keeping the instrument lightweight and incredibly easy to transport.
AeroSilk Piezo Pickup: Captures the elusive magic and "air" of a true acoustic upright, translating string vibrations into a deeply organic, woody thump.
Jatoba Fretboard: Boasts a gorgeous reddish-brown hue while producing a punchy, rich mid-range and a wonderfully crisp high end.
Built for Expression
It’s the meticulous hardware details that elevate an instrument from merely good to undeniably great. Ibanez custom-tailored the UB804’s bridge and electronics specifically to handle the unique dynamic range of both fingerstyle playing and arco bowing.
Custom AeroSilk MR5 Bridge: Features unique saddles designed to work in perfect harmony with the piezo system, enhancing the acoustic upright quality for both bowing and plucking.
Piezo Active Tone Control: Fine-tuned exclusively for the AeroSilk system, allowing you to dial in the perfect amount of boom, bite, and breath.
Gig-Ready Gear: Includes a heavy-duty TAMA Roadpro stand custom-built for the UB804, plus a padded gig bag that neatly swallows the bass, bow, and stand for one-trip load-ins.
Your Upright for Uncharted Territory
The Ibanez UB804 is what happens when passionate builders ignore convention and focus strictly on expression. It captures the soul and swagger of a classic upright while offering the playability and portability of a modern marvel. It’s an instrument built for players who want to break boundaries, command the stage, and explore the outer limits of low-end sound design.
