13-Pin Output Breakout

Roland/BOSS GK guitar synth interface


The 13-Pin Output Breakout Module sends polyphonic signals from your modular system to a Roland or BOSS guitar synthesizer.


It provides attenuated 6-channel outputs for each string signal as well as the passive pickup signal in order to match the levels typically produced by a GK hex pickup guitar. 


Standard GK CV signal inputs are provided to control the guitar synthesizer.

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

Hand-assembled in the USA.


  • Inputs for each signal in the 13-pin GK interface (audio and CV).

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

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

  • Low-noise audio op-amps for optimal AC performance.

  • Metal film resistors for close gain matching between channels.

  • Pairs well with 13-Pin Input Breakout, Hex VCA, Hex VCF, Hex Fuzz.

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