Settings
This chapter explains how to make the necessary settings when using the GR-55 for the rst time.
First, get your guitar/bass ready
•  In order to use the GR-55, you’ll need a guitar or bass equipped with a divided pickup (GK pickup), which 
outputs a separate signal for each string.  
You can use GK pickups such as the Roland GK-3 or GK-3B.
•  For details on how to install a GK pickup, refer to the owner’s manual that came with your GK pickup.
MEMO
•  Be aware that string buzz due to a warped neck or worn frets, or faulty octave adjustment, can cause 
problems such as wrong notes being produced.
•  This unit does not support 7-string guitars/basses or other non-standard guitars/basses.
NOTE
When you remove a GK-3 (GK-3B) from a guitar (bass) that has a lacquered nish, after it has been attached there for a long time, you may nd 
that it has left a mark on the surface.
Check the Web for details about installing GK pickups
•  On the Roland website, the “GK-3/3B Installation Tips” page provides an explanation and photos on how to 
attach a GK pickup. Be sure to take a look!
