Ibanez BTB625EX-BKF BTB 5-String Bass Guitar in Black Flat

The Ibanez BTB625EX-BKF is a no-nonsense, modern 5-string bass built for players who demand tight low end, rock-solid tuning stability and effortless playability across the entire neck. With its neck-through construction, extended 889 mm scale and fully blacked-out Iron Label aesthetic, this BTB is purpose-built for heavy styles where clarity, punch and precision are absolutely essential.

At its core, the BTB625EX-BKF combines a 5-piece Maple and Walnut neck with Okoume body wings and an Ebonol fretboard, delivering a fast, rigid platform that translates every nuance of your playing. Bartolini BH2 pickups and an Ibanez Custom 3-band active EQ give you a wide, modern tonal palette, from tight, focused lows to articulate mids and clear, controlled highs. Whether you are drop-tuning for djent, holding down progressive metal or laying down clean, hi-fi grooves, this bass is engineered to stay defined and powerful in any mix.

The extended upper fret access and stainless-steel medium frets make technical lines, chords and solos feel natural, while the MR5 Mono-Rail bridge maximises string isolation for enhanced note separation and sustain. Finished in a stealthy Black Flat satin polyurethane, the BTB625EX-BKF looks as aggressive as it sounds, with matching black hardware completing the Iron Label look.

Neck-through Power and Sustain

The neck-through construction runs the 5-piece Maple and Walnut neck all the way through the body, providing exceptional sustain and stability. This design also allows for a super-smooth heel and effortless access to all 24 frets, so complex lines and high-register runs feel comfortable and controlled.

Modern, Durable Playing Surface

An Ebonol fretboard paired with stainless-steel medium frets offers a slick, consistent playing surface that can handle low tunings and aggressive techniques. The combination delivers bright attack, excellent durability and a smooth feel under the fingers, ideal for fast, articulate playing.

Bartolini BH2 Pickups and Custom 3-band EQ

Dual Bartolini BH2 pickups provide a tight, punchy and modern voice with a strong low-mid presence that keeps your sound solid and defined. The Ibanez Custom Electronics 3-band active EQ with a 3-way mid frequency switch lets you fine-tune your tone for different genres and tunings, from scooped modern metal to mid-forward prog and fusion.

MR5 Mono-Rail Bridge and Iron Label Aesthetic

The MR5 Mono-Rail bridge isolates each string for improved clarity, sustain and precise intonation, particularly important when dealing with extended-range tunings. Finished in Black Flat with matching black hardware, the BTB625EX-BKF carries the aggressive, stealthy Iron Label look that fits perfectly on any modern stage.

• Neck-through Construction - The neck-through design enhances sustain and resonance while providing seamless upper fret access. This makes complex riffs, chords and solos higher up the neck feel natural and comfortable, even during long sets.
• Bartolini BH2 Pickups with 3-band Active EQ - The Bartolini BH2 pickups deliver a focused, punchy tone with tight lows and clear mids. Paired with the Ibanez Custom 3-band EQ and 3-way mid frequency switch, you can quickly sculpt your sound to cut through dense mixes or sit deep and supportive in the low end.
• Ebonol Fretboard with Stainless-steel Frets - The Ebonol fretboard offers a smooth, consistent feel and enhanced brightness, while stainless-steel medium frets provide long-lasting durability and a slick playing response. This combination is ideal for players who use heavy strings, low tunings or aggressive techniques.
• MR5 Mono-Rail Bridge - Each string has its own isolated bridge unit, improving note separation, sustain and tuning stability. This design helps keep complex chords and fast passages clear and defined, even when using extended-range tunings on the low B.
