Boss GKC-DA Guitar Synth Converter
The Boss GKC-DA Guitar Synth Converter is a specialised interface designed to bridge the gap between modern and legacy guitar synthesis technologies. It specifically allows players using the Boss GK-5 series digital pickups to connect to traditional 13-pin guitar synth hardware for a seamless performance setup.
See live pricesOverview
The Boss GKC-DA serves as a critical link in a modern guitar synthesis signal chain. As Boss transitioned its guitar synth ecosystem toward the new serial digital interface found in the GK-5 series, the GKC-DA was developed to ensure that players could still utilise their extensive libraries of legacy 13-pin equipment. It acts as a digital-to-analogue translator for polyphonic guitar signals.
Functionality and Key Features
The primary function of the GKC-DA is to convert the digital serial signal generated by a Boss GK-5 or GK-5B pickup into a standard 13-pin analogue format. This allows the high-speed, noise-resistant signal of modern pickups to trigger older synthesisers.
Key features include: * Dedicated input for the Boss Serial GK digital cable. * Standard 13-pin output for connection to legacy sound modules. * Compact, robust housing suitable for pedalboard integration. * Low-latency conversion to maintain the feel and response of the instrument.
Sound Character
As a utility converter, the GKC-DA does not possess a 'sound' in the traditional sense of an oscillator or filter. Its role is transparent conversion. By facilitating the use of the GK-5 pickup, it allows the user to benefit from the improved tracking and reduced interference of digital signal transmission while retaining the specific tonal characteristics of their chosen 13-pin sound module.
Target Audience
This device is primarily suited for guitarists and bassists who have upgraded their instruments with the latest Boss GK-5 pickups but still rely on classic 13-pin processors such as the Boss SY-1000, GP-10, or Roland GR-series modules. It is an essential component for those building a hybrid rig that spans multiple generations of guitar synthesis technology.
Comparison to Alternatives
Within the current Boss ecosystem, the GKC-DA is the inverse of the GKC-AD. While the GKC-AD converts old 13-pin signals for use with new digital processors (like the GM-800), the GKC-DA allows new pickups to drive old processors. Unlike standalone pedals like the Electro Harmonix Mono Synth, which process a standard 1/4-inch guitar signal into a single synth voice, the GKC-DA facilitates true polyphonic (individual string) synthesis by maintaining the multi-channel integrity of the GK system.

Frequently asked questions
- What is the main purpose of the Boss GKC-DA?
- The GKC-DA is designed to connect the newer Boss GK-5 series digital pickups to legacy guitar synthesiser gear that uses a 13-pin analogue connection. It acts as a bridge between serial digital and analogue multi-pin formats.
- Does this unit work with the Boss GK-5B bass pickup?
- Yes, it is compatible with the GK-5 series, which includes both the guitar (GK-5) and bass (GK-5B) versions of the serial digital pickup. It ensures bassists can also use legacy 13-pin gear.
- Can I use a standard 13-pin cable for the input of the GKC-DA?
- No, the input of the GKC-DA is designed specifically for the Boss Serial GK digital cable coming from a GK-5 series pickup. The 13-pin connection is located on the output side of the device.
- Will the GKC-DA add significant latency to my playing?
- The GKC-DA is engineered for high-speed conversion to ensure that the response remains seamless. It is designed to preserve the performance feel of the connected guitar synth gear.
- Does the GKC-DA require a power supply?
- Yes, as an active digital-to-analogue converter, the device requires power to operate. It is typically powered by a standard Boss 9V DC adapter.
- Can I connect a Roland GK-3 pickup directly to the GKC-DA?
- No, the GK-3 is an analogue 13-pin pickup. To connect a GK-3 to newer digital gear, you would need the GKC-AD converter, not the GKC-DA.
- Which Boss products are considered 'legacy' 13-pin gear for this device?
- Legacy products include units such as the Boss SY-1000, GP-10, and various Roland GR-series synthesizers like the GR-55 or GR-20. The GKC-DA allows these units to receive signals from new GK-5 pickups.
- Is the GKC-DA built for pedalboard use?
- Yes, the GKC-DA features a compact and durable metal chassis. Its footprint is designed to fit easily onto a standard effects pedalboard alongside other gear.
- Does the GKC-DA include a 13-pin cable?
- Typically, cables are sold separately. You will need a Boss Serial GK cable to connect the pickup to the GKC-DA and a standard 13-pin cable to connect the GKC-DA to your synth module.
- Can the GKC-DA be used with the GM-800?
- The GM-800 uses the new Serial GK digital system natively. You would only need the GKC-DA if you were trying to send the signal from your GK-5 pickup to an older 13-pin unit simultaneously or instead of the GM-800.
- What is the typical price for the Boss GKC-DA?
- The typical price range for the Boss GKC-DA is approximately GBP 148. Prices may vary slightly depending on the retailer and shipping costs.
- Does the GKC-DA support polyphonic processing?
- Yes, it supports full polyphonic conversion. It maintains the individual string signals provided by the GK-5 pickup, allowing for individual string processing on the 13-pin synth module.
