The A204 is a four string Affirma series solid body electric bass model introduced by Ibanez for 1992. It was produced in Japan.
The A204 features half through neck construction with a kralo walnut body attached to a maple neck with a 24-fret ebony fingerboard with offset abalone dot position markers at the twelfth fret and white side dots. The body has a sculpted, asymmetrical double cutaway design by swiss luthier Rolf Spuler with distinctive, narrow, curving horns; the AFR logo is inlaid into the guitar top between the pickup and bridge. Components include a single AFR 4 special single-coil pickup mounted halfway between the bridge, an AFR 2-band EQ w/ piezo active tone control, a Mono-rail IV bridge with "Stay D tune" and individual volume adjustable polyphonic piezo saddle pickups and 19mm string spacing, a barrel-style stereo output jack, a plastic nut and gotoh tuning machines.
Controls consist of individual volumes for the magnetic and piezo pickups, a stacked 2-band EQ for the magnetic pick and an active tone control for the piezos. The gain of each individual piezo can be adjusted via trimpots accessible from the back of the instrument.
The A204F is a similar fret-less version. The A205 is a similar five string version.
