Ibanez UB804-BUL Electric Upright Bass Guitar in Black Ice Burst Low Gloss

The Ibanez UB804-BUL is a sleek, modern take on the upright bass, designed to feel instantly familiar to electric bass players while delivering an expressive, acoustic-inspired voice. With its 34" scale, compact Maple body and AeroSilk piezo system, it offers a smooth transition from bass guitar into the world of upright playing, all wrapped up in a striking Black Ice Burst Low Gloss finish. Supplied with a dedicated gig bag and custom TAMA Roadpro stand, it is a complete performance-ready solution for stage, studio and practice.

Despite its compact footprint, the UB804 projects a robust, natural tone that captures the airy character of a traditional upright. The conical compound fingerboard radius is engineered for both fast pizzicato lines and fluid bowing, while the neck-through construction and 5-piece Maple/Walnut neck deliver clarity, sustain and a responsive feel. Whether you are a bassist looking to expand your palette or a doubler needing a portable, reliable upright-style instrument, the UB804 is built to inspire.

Effortless transition from electric to upright

The UB804 uses a familiar 34" scale length, making it far less intimidating for electric bass players moving into upright territory. The conical compound fingerboard radius supports both smooth bowing and agile plucking, so you can explore new techniques without fighting the instrument. White dot inlays help with quick visual navigation, ideal for live work and fast learning curves.

Compact body with big, natural tone

The compact Maple wing body is designed to balance form and function, offering excellent ergonomics and eye-catching aesthetics in the Black Ice Burst Low Gloss finish. Despite its smaller size, the UB804 does not compromise on acoustic character, delivering a robust, organic sound that sits beautifully in jazz, pop, theatre pits and beyond. The reduced footprint also makes transport and stage setup quick and straightforward.

AeroSilk piezo system & active tone control

At the heart of the UB804 is the custom AeroSilk piezo pickup and matching active tone circuit. The AeroSilk system is voiced to capture the sense of air and resonance that defines classic upright bass tone, while the dedicated Piezo active tone control lets you fine-tune the response for different rooms, ensembles and playing styles. From warm, woody thump to more articulate, modern clarity, the UB804 is ready to adapt.

Neck-through stability & premium playability

The 5-piece Maple/Walnut neck-through construction provides excellent sustain, stability and tonal focus. Finished in satin polyurethane, it feels fast and comfortable under the hand, encouraging long sessions without fatigue. The Jatoba fingerboard adds a rich midrange and crisp top end, complementing the AeroSilk system and ensuring every nuance of your playing is translated with precision.
