The EDA900 is an Ergodyne series solid body electric bass model introduced by Ibanez for 2001. It was produced in South Korea by Cor-Tek.
The EDA900 features a luthite body bolted to a maple neck with a 24-fret rosewood fingerboard with offset abalone dot position markers at the twelfth fret and white side dots. The body has a sculpted, asymmetrical double cutaway design with distinctive, narrow, curving horns; the logo is inlaid into the guitar top between the pickup and bridge. Components include a single "Ibanez Dynamix Full Range" DFR-N5 pickup mounted halfway between the bridge, an EQA-PZ system EQ with piezo active tone control, a Mono-rail II bridge with individual volume adjustable polyphonic piezo saddle pickups and 16.5mm string spacing, a barrel-style stereo output jack, a plastic nut and die-cast tuning machines.
