Change the setting to a value closer to “0” and check 
operation.
The built-in effects don’t work
Select a type other than “Off.”
Are the “REV SEND LEVEL,” “CHO SEND LEVEL,” 
and volume-related Multi-effect parameters set to 
appropriate values?
Set them to appropriate values.
Is the three-digit display blinking “Edt” to indicate 
that the unit is in EFFECT BYPASS mode?
The GR-33’s built-in effects are exclusively for use 
with the internal synth sounds. They are not applied to 
the sounds of the guitar itself.
You can apply external effects for the guitar to only the 
guitar sounds by using the GUITAR OUT jack. (If you 
wish to use a single amp for both the guitar and synth 
sounds, you should also use the GUITAR RETURN jack 
as well.) (p. 15)
If the “Cho Send Level (Chorus Send Level)” or “Rev 
Send Level (Reverb Send Level)” function is selected, 
make sure that the expression pedal (p. 47) is not 
rocked back all the way.
Depress the expression pedal.
The pitch of the synth sounds doesn’t 
change in the same way as the pitch 
of the guitar sounds
Some tones (such as percussion instruments and effect 
sounds) show different changes in pitch than with the 
guitar. This is not a defect.
If Harmonist is on, scale changes for synth sounds are 
different from the guitar when “HAR/ARP SELECT” 
(p. 82) is set to “Harmony All” or “Harmony 1&2.”
Noise with subtle undulations is hear 
in extremely high registers
This is a phenomenon peculiar to digital sound 
generators known as “aliasing noise.” It may be 
audible when using the slide technique or the Pitch 
Shift function, but it is not a defect. The GR-33 is 
designed to minimize such noise during guitar play.
Pitch doesn’t change smoothly
Is COMMON “CHROMATIC” set to a value from 
“Type1” to “Type3”?
Set CHROMATIC to “Off” for patches that require 
continuous changes in pitch (p. 42).
Is the Bend Data Thin function (p. 95) in use? Using 
this function may result in a slight loss of smoothness 
when pitch changes, even during normal play.
Do not use the Bend Data Thin function when it is not 
needed.
“Battery Low!” appears in the display 
when the power is switched on
This is a warning that means that the internal battery 
which maintains user patch and system setting data is 
almost dead. If this message appears, data may be lost 
is the battery is not replaced quickly.
Contact servicing by your dealer or qualified Roland 
service personnel.
When Changing Patch Settings
The display suddenly starts flashing
In a parameter where the [STRING SELECT] button is 
valid and you select “ALL” (all strings) or “5-6” (strings 
5 and 6), the blinking display indicates that the current 
settings differ between strings.
During EFFECTS editing, a blinking “Edt” indicates 
that the bypass function is ON.
The sound doesn’t vary when the 
settings are changed
the GR-33’s Attack, Release, and Brightness settings 
are intended to adjust the original data belonging to 
each tone. This means that the range of change differs 
according to the tone, and some tones may not show 
much of a change.
Is the setting being changed one of the seven settings 
that can be made independently for each string (see the 
following item), and is the setting affecting only a 
particular string?
Use the [STRING SELECT] button to set it to “ALL.” (p. 
35)
