The premium signature bass guitar designed for Gary Willis' discerning tastes.

Designed in collaboration with bass legend Gary Willis, the Ibanez GWB25TH signature bass offers the excellent playability, construction and versatile sound that the renowned artist demands. This signature bass features select tonewoods like ash and ebony paired with top-notch components to inspire your playing. The GWB25TH has a special detachable finger ramp—a revolutionary feature devised by Gary Willis himself to allow more consistent fingering attack. Outfitted with custom Bartolini pickups and a 2-band EQ, you get exceptional tonal control to craft your signature sound. Its three-piece maple neck reinforced with KTS titanium rods provides rock-solid stability you can count on. Plug in the Ibanez GWB25TH and experience the premium signature bass guitar designed for Gary Willis' discerning tastes.

Revolutionary Detachable Finger Ramp for Consistent Attack

What truly sets the Ibanez GWB25TH signature bass apart is the ingenious detachable finger ramp—designed by Gary Willis himself. Mounted just behind the E string, this ramp stops your fingers from digging in too deep. The result is a more consistent attack with quicker recovery time between notes. Easily removable, you can take off the finger ramp anytime you want a more conventional playing feel. This revolutionary add-on allows for more articulate and dynamic bass lines. No other production bass offers this kind of innovative solution for improving your attack technique.

Premium Wood Selection Produces Inspiring Tone

The GWB25TH sports a premium wood selection for excellent resonance and sustain. Its ash body provides a pleasant brightness while the ebony fingerboard outputs tight lows, strong mids and crisp highs. Combined with the Bartolini electronics, you have exceptional tonal control to craft your signature sound. The maple neck reinforced with KTS titanium rods offers rock-solid stability. Every component of the Ibanez GWB25TH is carefully chosen for optimal tone and playing comfort.

Powerful Bartolini Pickups and EQ for Custom Tone Shaping

To give you versatility, the Ibanez GWB25TH is equipped with custom Bartolini pickups and EQ electronics. The specialized pickups feature separate coils for balanced string response. The active 2-band EQ provides independent bass and treble boost/cut so you can dial in the ideal tone. An EQ bypass switch lets you toggle between active and passive modes. With this exceptional level of tonal control, you can craft signature tones all your own—from vintage growl to modern snap.

Stable 3-Piece Maple Neck for Confident Performance

The Ibanez GWB25TH has a three-piece maple neck reinforced with KTS titanium rods. This combination offers exceptional stability for confident performance time after time. The titanium rods add sustain and prevent the neck from warping under environmental changes. Tuning reliability is also excellent thanks to the precise Gotoh machine heads. The ebony fingerboard further enhances tone. Every component of the GWB25TH is designed for inspiring playability night after night.
