Boss GKC-DA Serial To 13pin Converter

A Gateway Between the 13-Pin GK Era and the New Serial GK Interface

For years, the 13-pin GK ecosystem has allowed guitarists and bassists to explore synthesis, modeling, and sound control via a dedicated connection. BOSS's latest guitar synthesizers now introduce Serial GK, a next-generation digital interface designed to offer a more modern connection and optimized performance. The BOSS GKC-DA fits precisely into this transition: it enables you to continue using 13-pin GK equipment while adopting a recent Serial GK source (divided pickup GK-5/GK-5B or GM-800 synthesizer).

In short, the GKC-DA occupies a strategic position in a hybrid setup: it avoids having to choose between old and new, and facilitates the coexistence of multiple BOSS and Roland devices within the same rig.

Who Benefits from the GKC-DA and in What Scenarios?

The GKC-DA is aimed at guitarists and bassists who want to enjoy the advantages of the Serial GK interface while retaining a processor or synthesizer based on the 13-pin GK connection. It is particularly relevant if you already own a device like the BOSS SY-1000 or the BOSS GP-10 and wish to control it from a GK-5, GK-5B (bass), or GM-800.

On stage, it simplifies setup changes and protects your investment in 13-pin gear. In the studio, it allows you to quickly leverage an existing production chain without reconfiguring all the wiring or giving up historical GK tools.

Key Features: Conversion, Routing, and Pedalboard-Friendly Design

Serial GK to 13-Pin GK Conversion

The heart of the GKC-DA is its ability to convert the digital Serial GK interface into the analog 13-pin GK interface. This conversion makes it possible to use a recent Serial GK source with a 13-pin GK device while preserving the connection logic expected by BOSS and Roland units compatible with 13-pin GK.

Instrument Input: Transmission of the "Normal Sound" to the 13-Pin Output

The GKC-DA includes an instrument input that allows transmission of the normal sounds of a guitar or bass to the 13-pin GK output. This is essential for GK setups, where both the "divided" signal (for synthesis/modeling) and the instrument's standard signal are often used. This architecture facilitates integration into an existing system, maintaining a clear approach to routing and connections.

Compact and Robust Metal Enclosure

Designed for real use (rehearsals, tours, frequent setup/teardown), the GKC-DA features a metal construction in a compact format. It easily fits on a pedalboard or near a multi-effects unit/synth and aims for durability consistent with the needs of musicians who regularly transport their gear.
