13-Pin Input Breakout

Roland/BOSS GK guitar interface for hexaphonic or polyphonic processing

Overview:

The 13-Pin Input Breakout module receives signals from a Roland GK-3 compatible guitar and converts them to modular levels using low-noise audio op-amps.

​

Gain options include 10x (20dB), 30x (30dB), or 100x (40dB).

​

Gain controls allow you to adjust the gain from zero to full-scale in the amplified string outputs.

​

Amplifier boards are easily replaceable with different gain versions.  Check the shop for replacement boards.

​

The module provides power to the electronics in your GK-3 compatible guitar.

​

Hand-assembled in the USA.

Important Note:

This module has been tested successfully with Roland GK-3, GK-2A, Graph Tech Hexpander, and RMC Poly-Drive pickup systems.

​

Roland GK-2A pickups (including those on the Fender GC-1) require a special version of this module.

 

Please indicate if you intend to use a Roland-ready or GC-1 Stratocaster with this module at the time of your order and we will supply the special version.

​

Guitars equipped with L.R.Baggs piezo pickups (such as Godin's new SA models) will not work with this version of the module due to impedance mismatches!

​

There is a workaround for the L.R.Baggs issue. Please contact us for more details.

 

We are developing a new module revision that will address both issues mentioned above.

Features:

  • Outputs for each signal in the 13-pin GK-3 interface (audio/CV).

  • Access to direct signals from each string and the passive pickup.

  • Selectable gain range (1x or 10x, 30x, 100x) for each string and the passive pickup output on back of the module.

  • Adjustable gain or attenuation to zero within each selected gain range.

  • Metal film resistors for close channel gain matching.

  • Pairs well with 13-Pin Output Breakout , Hex VU Meter, Hex Fuzz, Hex VCF, Hex VCA, and Hex EF-Gate-Trigger.

  • Ideal for guitar multi-channel, single-string, or hexaphonic effects processing.

  • The Amplifier-Attenuator section may be used independently by introducing signals via the front panel input jacks or SynQuaNon Audio Bus input connection in the back.

  • Version 3 of the module features the latest SynQuaNon Audio Bus connections on the rear.
