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
phaseshifted signal to the direct
sound, giving the sound a swirling
character.
TREMOLO
Tremolo is an effect that creates a
cyclic change in volume.

13. POWER SQUEEZER Switch
The switch lights in red when the power squeezer
function is on; the switch is unlit when the power
squeezer is off.
Switching on the Power Squeezer function allows you to
reduce the amp's output to 2 watts.
Switching this on allows you to produce a sound that
preserves the same tone and balance as when the amp is
played at maximum volume, but at an output of 2 watts,
for volume levels that are more suitable for the average
home.
* The Power Squeezer function affects only sounds input
through the INPUT jack. It has no effect on sounds input via
the AUX IN jack.
14. AUX IN Jack
You can connect a CD player, MP3 player or other kind
of device and have it play along with your guitar.
This accepts a stereo miniature phone plug. However,
the speaker and RECORDING OUT/PHONES output is
monaural.
* Determine the volume level by adjusting the volume control of
the connected device.
15. FOOT SW (Footswitch) Jack
You can use footswitches (optional BOSS FS-5U or FS-6)
connected using a connection cable (optional Roland
PCS-31) to switch channels (JC CLEAN/LEAD), and to
turn EFX on and off.
