Key Switch; Volume Knob; Power Indicator - Roland MICRO CUBE MICRO CUBE Guitar Amplifier Owner's Manual

3. GAIN Knob
Adjusts the sensitivity at the input jacks.

4. VOLUME Knob

Adjusts the volume.

5. Power Indicator

This indicator lights when the unit is turned on.
* When operating on battery power only, the unit's indicator will
become dim during play when battery power gets too low.
* Sounds may distort easily or may cut off when played at
high volume as the battery power begins to fade, but this
is normal and does not indicate a malfunction.
In such instances, either replace the batteries or use the
AC adaptor included with the unit.
6. TUNING FORK Switch
Press the switch to play the modeled tuning
fork sound. Use this tone as the reference
pitch when tuning your guitar.
The tuning fork volume is changed by how hard
you press the switch. Adjust the overall volume
with the GAIN knob ( 3 ) and VOLUME knob ( 4 ).
* Pressing the TUNING FORK switch forcefully with the
3
GAIN knob ( ) and VOLUME knob (
cause a sudden increase in volume. Be sure to monitor
your volume levels carefully when using the amp at night
and in other cases where high volumes should be avoided.
● Select the tuning fork pitch with the KEY switch (7).
Select "A" for normal tuning. Use the following
procedure to tune your instrument.
1. Press the TUNING FORK switch to start the
tuning fork sound.
2. Play the harmonic at the fifth fret of the fifth
string over the tuning fork sound.
A wavering or "beating" pattern will be audible if
the tuning fork and string are not in tune.
3. Adjust the fifth string until the beats disappear.
4. After tuning the fifth string to A, tune the other
strings in reference to the fifth string.
● You'll find using the tuning fork easier if you use
the TYPE switch (2) to select JC CLEAN or some
other tone that does not include distortion, and turn
the EFX and DELAY/REVERB to OFF.
● The tuning fork will continue sounding for a while
after you push the TUNING FORK switch. Push the
switch in gently to stop the sound in the middle of a
continuing note; the duration of the tuning fork sound
will be shortened, and it will stop briefly later.
