10. 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.
CHORUS (spacially synthesized chorus)
This uses the same spacially synthesized
chorus as the JC-120 to deliver a broad
sound.
* The chorus effects are designed so
they exhibit the greatest effectiveness when you use the unit's
built-in speakers. Effectiveness may differ when REC OUT/
PHONE are used instead of the built-in speakers.
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.
* Graduations for CHORUS, FLANGER,
PHASER and TREMOLO on the panel
are for reference. Be sure to check the sound as you adjust the effects.
11. DELAY/REVERB Knob
Turn this knob to DELAY or REVERB to switch to that effect.
You can also adjust the amount of effect applied by turning
the knob to the desired position.
DELAY
Turn the knob to adjust the delay effect.
REVERB

* Graduations for DELAY and REVERB
on the panel are for reference. Be sure to
check the sound as you adjust the effects.
12. RHYTHM GUIDE
The unit is equipped with drum/percussion-based rhythm patterns
that are useful for solo practicing. In addition to practicing with your
desired beat, you can also use it as a metronome.
