Ibanez SRD900-CTL Cosmic Blue Starburst Low Gloss Bass Workshop

An SRD Designed to Bridge Electric and Upright Playing

The SRD900 fits within the spirit of modern performance-oriented basses by adding an "acoustic/upright" dimension thanks to the AeroSilk Piezo system integrated into the bridge. The goal is clear: maintain the ergonomics of an electric bass while offering a more organic and airy response when desired, without sacrificing the power and definition of a magnetic pickup set.

For Which Bassists and Styles

This Ibanez targets intermediate to advanced bassists who want to cover a wide range of genres: pop, modern rock, fusion, neo-soul, electric jazz, worship, and any situation alternating between punchy attacks and more "woody" nuances. With its 24 frets, it remains very comfortable for melodic lines and playing in the upper register, while maintaining excellent control in the low end.

Sound Characteristics

The combination of a exotic maple top and okoumé body promotes a clear, fast, and articulate sound: maple adds brightness and attack, while okoumé helps keep a present low-midrange and good resonance. The Nordstrand Big Break pickups (soapbar format) deliver a dense and muscular texture with clarity that remains readable in a mix. Meanwhile, the AeroSilk piezo adds "air" and a more acoustic component, ideal for expressive finger attacks and subtler passages. The 2-band EQ on the pickups (bass/treble) and dedicated piezo control allow precise balancing between electric punch and "upright" feel.

Recommended Compatible Accessories

For transport, the MB300C (case) and IBB540-BK (gig bag) are recommended. To preserve the original feel and tone, prefer D'Addario ECB81 flatwound strings in .045/.065/.085/.105 gauge when replacing strings.
