Ibanez SDGB1-DMT Steve DiGiorgio Signature Fretless 5-String in Bass Guitar in Dark Moss Burst

The Ibanez SDGB1-DMT is the fretless 5-string signature bass of metal legend Steve Di Giorgio, crafted for players who demand singing sustain, piano-like clarity and surgical note definition. With a neck-through 9-piece construction, Nordstrand Big Single pickups and a fully flexible Vari-Mid 3-band EQ, this Dark Moss Burst beast is built to cut through the densest mixes while still delivering all the nuance and expression that fretless playing is known for.

From the first note, the SDGB1-DMT feels fast, solid and incredibly responsive. The multi-laminate neck and Mono-Rail V bridge work together to maximise sustain and string separation, while the Ebonol fretless fingerboard lets you glide effortlessly between notes with vocal-like slides and vibrato. Whether you are anchoring complex progressive arrangements or unleashing fluid solos, this bass gives you the articulation and control to be heard clearly in any context.

Tonally, the combination of Nordstrand Big Singles and the Ibanez Vari-Mid 3-band EQ gives you a huge range of usable sounds, from tight, aggressive growl to warm, singing mids and smooth top-end sheen. A dedicated passive mode with its own tone control keeps you covered if you prefer a more traditional response or want a quick, reliable backup when the battery is out of the circuit. Visually, the flamed Maple top with Ash/Okoume wings in Dark Moss Burst and cosmo black hardware complete a look that is as serious as the performance.

Neck-through Power and Sustain

The 9-piece Maple/Bubinga/Panga Panga neck runs right through the body, creating a rigid, stable core that enhances sustain and resonance. Graphite reinforcement adds extra stiffness and reliability, helping the neck stay true under stage lights and heavy string tension. The result is a bass that rings out clearly, with consistent response across all five strings and up the entire scale length.

Expressive Fretless Ebonol Fingerboard

The smooth Ebonol fretless fingerboard is designed for fluid, expressive playing, letting you shape every note with slides, vibrato and microtonal inflections. Its hard, consistent surface offers a bright, articulate attack that helps fretless lines sit clearly in the mix, while still retaining the singing, vocal quality that fretless players love.

Nordstrand Big Single Pickups with Vari-Mid EQ

A pair of Nordstrand Big Single pickups delivers a powerful, modern single-coil voice with plenty of punch, clarity and definition. Paired with the Vari-Mid 3-band EQ and selectable mid frequency, you can precisely sculpt your sound to fit any genre or mix, from tight, scooped tones to forward, growling mids that cut through complex arrangements.

Mono-Rail V Bridge and Premium Body Construction

The Mono-Rail V bridge isolates each string on its own saddle, improving note separation, intonation accuracy and overall clarity. Combined with the flamed Maple top and Ash/Okoume body wings, the SDGB1-DMT offers a balanced tonal foundation with tight lows, articulate mids and a clear, defined top end that responds beautifully to both fingerstyle and pick playing.

• 9-piece Neck-through Construction - The Maple/Bubinga/Panga Panga 9-piece neck with graphite reinforcement runs through the body for exceptional sustain, stability and upper-fret access, giving you a solid, consistent feel across all registers.
• Fretless Ebonol Fingerboard - The smooth Ebonol surface allows effortless slides and expressive vibrato while providing a bright, articulate attack that helps your fretless lines remain clear and defined in the mix.
