GWB1005

GWB1005 Natural Flat

The GWB1005 is a five string solid body electric bass model introduced by Ibanez for 2006, replacing the similar, South Korean-made GWB105. It is a signature model for American jazz fusion bassist Gary Willis. It is produced in Japan by FujiGen.

The GWB1005 features an Soundgear series double-cutaway swamp ash body bolted to a maple neck with a fretless ebony fingerboard with offset white dot position markers. Components include a custom Bartolini passive soapbar bass pickup with a Bartolini preamp with a two-band EQ, a standard bridge with 16.5mm string spacing, a removable finger rest/ramp, a plastic nut, and Gotoh tuners with custom Sure Grip buttons.

The GWB205 is a more affordable version of this bass which was made in Indonesia.
