Roland GK-3B Divided Bass Pickup

Roland GK-3B Divided Bass Pickup for 4-, 5-, and 6-String Basses

The Roland GK-3B divided bass pickup equips compatible 4-, 5-, and 6-string electric basses for use with Roland GK-compatible synthesizer and modeling systems. Its low-profile divided pickup senses individual string vibration, while the separate controller provides GK volume, sound-selection, and remote-control switches directly from the instrument.

Designed for bassists expanding beyond conventional magnetic-pickup tones, the GK-3B works with bass-synth and GK processing systems such as Roland V-Bass and GR-55 equipment. The pickup supports basses with approximately 0.6" to 0.7" string spacing, and the supplied mounting hardware provides installation options for a wide range of instrument designs.

A large GK Volume knob provides convenient level adjustment, while DOWN/S1 and UP/S2 switches allow compatible connected equipment to be controlled without reaching for a floor or rack unit. The Select switch lets the player choose the normal bass signal, the GK-generated sound, or a combination of both, making the GK-3B a flexible interface for synth-bass and modeling workflows.

Key Features

• Divided Bass Pickup: Detects individual bass-string vibration for compatible Roland GK synthesizer and modeling equipment.
• 4-, 5-, and 6-String Compatibility: Designed to fit most common electric bass configurations rather than being limited to four-string instruments.
• Adjustable String Spacing: Supports basses with approximately 0.6" to 0.7" spacing between strings.
• On-Bass GK Volume: Large smooth-action control provides convenient adjustment of the connected GK device from the instrument.
• Three-Way Sound Selection: Selects the normal bass signal, GK sound, or a mixture of both from the controller.
• Remote Control Switches: DOWN/S1 and UP/S2 switches provide direct control of supported functions on compatible GK equipment.
• Flexible Installation: Includes an attachment holder, double-sided tape, and additional installation parts for mounting to different bass designs.
• Low-Profile Pickup: The divided pickup measures approximately 0.4" high, supporting installation close to the bridge and strings.

Individual String Detection for GK Systems

Unlike a conventional bass pickup that combines all strings into a standard instrument signal, the GK-3B uses a divided pickup to detect individual string vibration. This provides the information required by compatible GK processors and synthesizer systems for pitch-based processing, modeling, and synthesized bass sounds.

On-Instrument Synth and Bass Control

The controller keeps frequently used functions within reach of the picking hand. GK Volume adjusts the connected system level, while the Select switch changes between normal bass, GK sound, and mixed operation. DOWN/S1 and UP/S2 switches can operate supported functions on the connected GK device.

Fits a Range of Bass Configurations

Roland specifies compatibility with most 4-, 5-, and 6-string basses. The divided pickup includes string-spacing adjustment and supports instruments with approximately 0.6" to 0.7" spacing, helping the pickup elements align correctly beneath different bass-string layouts.

Flexible Mounting Options

The GK-3B includes an attachment holder, double-sided tape, and installation parts for adapting the system to different instruments. The controller measures approximately 3.4" wide, 2.9" deep, and 0.9" high, while the pickup itself spans approximately 5.4" across its maximum width.
