Ibanez GWB20TH Gary Willis Signature Fretless

 Ibanez GWB20TH Gary Willis Signature Fretless

It has been two decades since Ibanez first introduced the Gary Willis Signature bass, the GWB1, in 1999. We are extremely pleased to introduce the Gary Willis signature anniversary model, the GWB20TH, to celebrate the long and fruitful relationship.

GWB20TH has icons of Gary’s signature details such as a fretless fingerboard, finger ramp and special shaped machinehead. On top of those familiar GWB features, this anniversary model is unique unto itself. The Ash top/Basswood body provides sparkling highs and a well-balanced tone together with the Aguilar® DCB® pickup and OBP-2 preamp, and the beautiful TQF (Tequila Sunrise Flat) finish enhances the gorgeous Ash grain.
