GK Power in a Twin Pedal Stompbox
With the all-new V-Guitar pedals, guitarists can now enjoy the immense benefits of Roland’s GK processing—the powerful technology behind the GR-55 Guitar Synthesizer and VG-99 V-Guitar System—right on their pedalboards. The GR-D V-Guitar Distortion offers unique distortion and synth tones produced by independently processing each guitar string, giving the modern player an array of fresh, bold sounds for their sonic arsenal. Housed in the popular Twin Pedal format and equipped with connections for easy integration with amps, stomps, multi-effects, and other V-Guitar devices, the GR-D delivers wide, heavy, high-clarity tones that can only be achieved with GK processing.

WELCOME TO THE FAMILY
The GR-D V-Guitar Distortion joins Roland’s acclaimed V-Guitar family, which also includes the GR-55 Guitar Synthesizer and VG-99 V-Guitar System. The convenient stompbox format of the GR-D allows players with traditional setups to experience the incredible sound potential available with GK processing. When used with an optional US-20 Unit Selector, the GR-D also gives current GR and VG users new sounds for their existing rig.
UNLOCK ALL-NEW SOUNDS WITH GK PROCESSING
The GR-D features a 13-pin input for use with a guitar outfitted with a Roland GK-3 Divided Pickup or a GK-equipped instrument such as the GC-1 GK-Ready Stratocaster. Unlike standard monophonic guitar pickups, the Roland GK pickup senses and isolates each individual string, sending them as six discrete signals to a 13-pin jack. When connected to a V-Guitar device like the GR-D pedal, each string can be processed individually, opening up a universe of sound possibilities that are impossible with a normal 1/4-inch guitar output.
BOLD DISTORTION TONES FOR MODERN PLAYERS
Inside the GR-D is a huge array of unique distortion colors made possible with GK processing. By applying separate distortion processing to each string, the atonal harmonic artifacts of mono distortion are completely eliminated. This results in incredible string definition and clarity, even with full, complex chords and extremely high levels of gain. In addition, picking dynamics are greatly enhanced, and wide stereo effects can be achieved. VG-DIST 1 and VG-DIST 2 offer two very different distortion flavors newly developed for the GR-D, while POLY DIST is a new variant on the classic “polyphonic distortion” in early Roland guitar synths, enhanced with the power of modern digital technology. SYNTH is an analog synth-type sound based on string vibration instead of an oscillator, providing an ultra-responsive playing feel with true guitar expressiveness.
TWEAK AND STORE YOUR CUSTOM SOUNDS
Like a normal stompbox, the GR-D features simple controls that are quick and intuitive to use, but behind their simplicity is an enormous range of sound-shaping potential. When you turn the GAIN, COLOR, and TONE knobs, you’re actually tweaking multiple under-the-hood parameters specifically tailored to each sound type, letting you achieve substantial tonal shifts even with small changes. Four memory locations let you store your favorite sounds, with quick recall via the control switches on your GK-equipped guitar. A Solo function, accessible with one of the pedal’s two footswitches, gives you an instant boost of volume and presence for lead playing.
EASY INTEGRATION WITH ANY RIG
The GR-D offers a multitude of connections for integrating with different rigs, including pedalboards, multi-effects setups, racks, mixers, and other V-Guitar devices. A dual MIX/GUITAR INPUT allows you to connect devices and blend them with the GR-D sound, with the combined mix sent to the pedal’s mono/stereo output. The 13-pin GK output carries the guitar’s normal pickup signal as well, and controls on the GK-equipped guitar allow you to blend the GK and normal sounds right from your instrument. A dedicated GUITAR OUTPUT jack on the GR-D lets you connect the normal guitar sound directly to an amp or effects with no GK processing applied. It can also be used in conjunction with the MIX/GUITAR INPUT to create a send/return loop for your normal effects chain.
GK-READY GUITARS AND OPTIONS
With its built-in GK pickup and 13-pin output, Roland’s popular GC-1 GK-Ready Stratocaster is a perfect fit for the GR-D, and there are GK-equipped guitars available from many other manufacturers as well. Roland also offers the GK-3 Divided Pickup, allowing you to easily add GK compatibility to your favorite guitar with no modification.
