Main Features
Dedicated eects unit for the V-Guitar/GK pickup
The GR-S is an eects unit specically designed for the GK pickup, which individually extracts the signal of each string.
Since each string’s signal is processed individually, you’ll be able to experience completely new sounds that could not
be produced by guitars with conventional pickups of the past.
Richly expressive sounds
The GR-S processes the signal from each string individually, generating sparkling and spacious sounds that have never
been heard until now. You’ll obtain expressive and extraordinary sounds not only when playing chords and arpeggios,
but even for single notes.
Simple operation
Operation is eortless. Just twist the knobs and press the pedals to obtain cutting-edge V-Guitar sounds.
Memory function
Four eects settings can be stored (in memory) in the unit. You can switch memory slots using the [S1] [S2] buttons of
the GK pickup for instant sound selection during your live performances.
Check the following points before using the GR-S
You’ll need a GK-compatible guitar
In order to use the GR-S, you’ll need a guitar equipped with a GK pickup or a GK-compatible guitar such as the
GC-1 V-Guitar. (Hereafter, we’ll refer to such a guitar as a “GK-compatible guitar.”)
* The GR-S does not support basses (GK-3B).
You must set the GK pickup select switch to the “MIX” position!
If the switch is set to any position other than MIX, the unit won’t operate correctly (there will be no sound).
