Ibanez and world-renowned jazz fusion bassist Gary Willis present the Ibanez GWB205. The Gary Willis Signature model was first introduced in 1999. Now, 20 years later, this latest incarnation comes as a result of years of improvements and tweaking. The GWB205 is a 5-string fretless bass that is sure to please any who play it. Featuring Gary's signature specs such as a fretless ebony fingerboard with fret-line markers, a detachable finger ramp dubbed the Willis Ramp, and custom Bartolini electronics, the GWB205 is a jazz fusion bassists dream come true.

Fretless Ebony Fingerboard with Fret-Line Markers
Popularized by legendary jazz bassist Jaco Pastorius, the fretless bass has grown to become a favorite amongst the jazz fusion community. The Ibanez GWB205 features a fretless ebony fingerboard with white inlaid fret line markers and offset front and side dot positions. Sitting on a 3-piece maple neck with a custom GWB profile, you can be sure your fingers are going to fly when you play this bass.

The Willis Ramp
The Willis Ramp is a key component of Gary's right-hand technique. The custom shape is designed to enhance not only the feel, but the sound of the bass. Most players tend to play over the pickup out of necessity as it provides a place to rest your thumb. The Willis Ramp makes the area above the pickup a more playable area. This helps to change your sound as well as the closer you move towards the neck, the fuller and more melodic your notes become. The Willis Ramp is contoured to the fingerboard radius so that you can play anywhere from the pickup to the neck and your right hand will feel exactly the same.

Custom Bartolini Electronics
Built custom for Ibanez, the Gary Willis signature Bartolini pickup is an extremely versatile humbucking pickup. Active electronics allow you to shape your tone to best fit the gig. The Bartolini NTBT Active 2-band EQ features a stacked pot allows you to adjust treble and bass as needed, and a master volume control featuring a pull-bypass switch. This allows you to bypass the EQ controls and run the pickup directly to the output jack for a nice volume boost.
