Ibanez SDGB1 Steve Di Giorgo Sign Dark Moss Burst

Ibanez SDGB1-DMT – 5-String Fretless Signature Bass in Dark Moss Burst

Steve Di Giorgio Signature Model

Built with an icon of extreme metal and fusion

The SDGB1-DMT is the signature model of Steve Di Giorgio—renowned bassist known for his work with Testament, Death, and many others. With a career spanning over 30 years and credits on more than 50 albums, Steve is recognized for his technical mastery and genre-spanning versatility, from thrash and death metal to jazz and fusion. When it came time to create a bass that could handle any musical scenario, Steve teamed up with Ibanez, drawing heavily from the BTB series to craft this custom model.

Precision and expressive tone – without frets

The SDGB1-DMT is a fretless 5-string bass featuring a 9-piece neck-through construction made from maple, bubinga, and panga panga, reinforced with graphite rods for added stability. The body wings are ash and okoume, topped with flamed maple for a striking look. The ebonol fretboard offers a smooth, articulate tone with enhanced clarity and warmth. Equipped with Nordstrand Big Single pickups in both neck and bridge positions, this bass delivers a bold, dynamic sound that’s easily shaped using the Vari-Mid 3-band EQ with bypass and passive tone control. The MR-5 bridge offers 19 mm string spacing for excellent intonation and comfort for technical playing styles.
