For decades, Ibanez has been one of the industry's most innovative manufacturers, constantly pushing the boundaries of instrument design. While the Japanese brand has become a benchmark in the world of electric guitars and basses, it has also earned an outstanding reputation through its Bass Workshop series—a creative platform dedicated to developing unique instruments tailored to the needs of demanding musicians. The UB805 perfectly embodies this philosophy: a five-string electric upright bass designed to deliver the expressiveness of a traditional upright while offering all the advantages of modern technology.

Far less common than conventional electric basses, electric upright basses occupy a unique niche in today's market. They appeal to players seeking the warm, singing voice of an acoustic upright without its size, fragility, or amplification challenges. With the UB805, Ibanez delivers an exceptionally refined instrument that feels equally at home on stage, in the studio, or during everyday practice.

The first impression is one of elegance and premium craftsmanship. Its beautiful Mahogany Oil Burst finish enhances the instrument's sleek lines while emphasizing its distinctive personality. Compact, lightweight, and easy to transport, it nevertheless retains an ergonomic design that immediately recalls the feel of a traditional upright bass, allowing players to adapt naturally within minutes.

Its construction inspires confidence from the very first notes. The five-piece maple and walnut neck-through design provides outstanding rigidity, maximizes vibration transfer, and delivers impressive sustain. Combined with the maple body wings and jatoba fingerboard, it creates an instrument that is remarkably responsive, articulate, and well balanced, capable of reproducing both powerful attacks and the most delicate musical nuances.

Ibanez equips the UB805 with its AeroSilk Piezo system, specifically engineered to recreate the natural behavior of an acoustic upright bass with exceptional realism. The results are highly convincing: deep, full-bodied lows, rich and expressive mids, and smooth, controlled highs. Every detail of the player's touch is faithfully reproduced, whether playing pizzicato or with a bow, making the instrument equally suited to jazz, classical music, world music, contemporary productions, and countless other styles.

One of the greatest strengths of this version is its five-string configuration. The addition of the low B string significantly expands the instrument's range, an increasingly valuable feature in modern musical settings. This extended register adds greater depth to bass lines, allows more efficient fingering positions, and opens the door to a broader repertoire without compromise. Whether performing orchestral music, gospel, fusion, film scores, or contemporary arrangements, the fifth string provides an impressive reserve of low-end frequencies that greatly enhances the instrument's musical versatility.

Its 34-inch scale length makes the transition particularly natural for electric bass players, while the fretless fingerboard preserves all the expressive subtlety that defines the upright bass. Smooth slides, vocal-like vibrato, and precise microtonal control all contribute to the instrument's unmistakable personality, encouraging an expressive and highly musical playing style.

Rather than simply imitating a traditional upright bass, the UB805 offers a fresh and highly practical interpretation of the instrument while remaining faithful to its musical essence. Its compact format, refined electronics, and premium construction make it an outstanding choice for professional musicians as well as passionate players looking for something truly different.

Rare on today's market, beautifully engineered, and blessed with a distinctive sonic identity, the Ibanez UB805 is far more than just a fretless bass. It is an instrument with genuine character, capable of bringing an entirely new dimension to your playing through its realism, musicality, and the extended range provided by its fifth string. An original and inspiring creation for musicians seeking an instrument that stands apart from the ordinary.
