What is it?
The GK Wireless system is a wireless cable solution for use with a divided pickup from Roland(GK-2, GK-3) or Godin (SA). The GKW system consists of a sender- and receiver unit that can replace the 13 pin DIN cable between a guitar and an effect unit. It is capable of wireless transmission of 6 divided pickup outputs, regular pickup output and control signals; up, down, volume and mode switch. Hence, it will give more freedom of movement to a guitar player who wants to use a guitar synthesizer or -modeler (Roland GR-55, VG-99, etc). It is also more reliable than a long 13-pin DIN cable as these cables tend to be heavy and prone to bad connections.

GKW Sender
The GKW sender unit must be connected to your GK-3 divided pickup with a 1 meter long 13 pin DIN cable with locking plugs, which is included in the product.

Generic GK divided pickup not included


The GKW sender unit has a belt bracket so that you can conveniently clip it to your guitar belt.

Two 18650 batteries (3.7V) are used as a power source for the GKW sender. The sender consumes about 500mA, hence when using 3500mAh batteries you will have about 7 hours of playing time. Standard replaceable batteries were chosen in this design, so that you can easily insert fresh spare batteries while recharging the depleted ones. Batteries are not included with the GKW product as there are too many shipping restrictions for lithium batteries. But 18650 batteries are widely available in any country. SAFETY WARNING: Make sure you only use protected 18650 batteries with a button top.

Batteries not included

GKW Receiver
The GKW receiver unit must be connected to the guitar synthesizer or modeler with a short standard 13-pin DIN mini cable, which is included in the product.

Power adapter not included

Any 5V - 20V DC power adapter, negative center, 300mA or more, can be used as a power source for the GKW receiver. A power adapter is not included with the GKW product, because the country requirements for power sockets are different all over the world. It is easier to buy a cheap universal power adapter at your local store. It is recommended to use a DC 9V, negative centered power adapter, like usually used with guitar effect pedals.
