Panel Descriptions
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
GAIN knob (
3
) and VOLUME knob (
4
) turned up may
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.
7. KEY Switch
Use this to select the tuning fork pitch. Select
“A” for normal tuning. To drop the tuning a
half-step (semitone), select A , or select A
to lower the tuning a full step (whole tone) (A
= 440 Hz).
8. TONE Knob
This adjusts the tone. Turn the knob
clockwise for a brighter tone; to get a milder
tone, turn the knob counterclockwise.
9. EFX (Effects) Knob
Turn this knob to chorus, flanger, phaser, or
tremolo to select the corresponding effect.
Turn the knob to adjust the amount of effect
applied.
*
Graduations for CHORUS, FLANGER, PHASER,
TREMOLO on a panel are for reference. Be sure to check
the sound as you adjust the effects.
CHORUS
In this effect, a slightly detuned sound is
added to the original sound, giving the
sound greater breadth and fullness.
FLANGER
This creates a flanging effect that creates a
sort of spinning sensation with the sound.
PHASER
This effect adds a variable phase-shifted
signal to the direct sound, giving the sound a
swirling character.
TREMOLO
Tremolo is an effect that creates a cyclic
change in volume.
10. DELAY/REVERB Knob
Turn this knob to DELAY or REVERB to
switch to that effect. Turn the knob to adjust
the amount of effect applied.
