LEVEL
This controls output level of effected
signal. Typically output levels of both
normal signal and effected signal
should be adjusted to equal levels.
⑥
BOOST/NORMAL
Switch for BOOST/NORMAL. In BOOST
mode, it provides tube sound in which
mid-range is boosted by 3 dB.
In NORMAL mode, classical tube sound
is available.
⑦
FOOTSWITCH
Switch for effect/bypass. Stepping on this
switch alternately turns effects on and off.
* Effect turns on when you depress the
switch and effect turns off when you
depress and release the switch.

LED INDICATOR
This indicates the effect/bypass status
and battery condition. It lights when plug
is inserted to input jack and effect is on.
No LED light indicates the battery is low
or not installed. In this case replace
the battery.
⑨
DC IN (power input jack)
Jack for connection of external
power supply to effect. Be sure to
use the correct Maxon AC adaptor.
For further information on AC adaptor,
refer to page 26.
Turn down amplifier’s volume
to the minimum before con-
necting AC adaptor or DC plug.
⑩
OPERATING VOLTAGE SWITCH
Slide it to left side for 18V (
±
9V)
and right side for 9V (
±
4.5V).
Turn down amplifier’s volume
to the minimum before sliding
this switch.
⑪
INTERNAL LED INDICATOR
This indicates the status of operat-
ing voltage. It lights at 9V (
±
4.5V).
No LED light indicates the operat-
ing voltage is 18V (
±
9V).
ment. can also be used at 9 volts (plus and minus 4.5 volts). Stable
sound is constantly available regardless of selected voltage.
