Nexus® GK Attenuator

Cycfi Research Nu Multi to Roland/BOSS GK input matching


The GK Attenuator installs in a Cycfi Research Nexus® Breakout Box between the incoming string audio channels and a user-installed Roland/BOSS GK 13-pin jack or GK Internal Kit.

Allows for better signal level matching between Cycfi Research Nu Multi® pickups and Roland/BOSS guitar synthesizers.

A custom Synth-Linx® GK cable assembly is also available for DIY GK jack installation.  This cable has a connector for the GK attenuator and signal ground, along with individual connectors for all other 13-pin signals.  The latter allows one to customize the Nexus® channels used for GK control voltages and power.


Note that you will need to drill the Nexus® front panel in order to install the Synth-Linx® Jack.  See Nexus® GK Upgrade Custom Installation if you prefer to have SynQuaNon perform the installation.

Hand-assembled in the USA.
