* If this indicator goes dim or no longer lights while
an effect is ON, the battery is near exhaustion and
should be replaced immediately. For instructions on
changing the battery, refer to "Changing the
Battery" (p. 12).

being applied or not. It does not indicate whether
the power to the device is on or not.

The output jacks are used to connect the unit
to an amplifier or another effects unit.

Sound Separately" (p. 11).
4. GUITAR IN Jack, BASS IN Jack
These jacks accept input signals (coming
from a guitar, a bass, some other musical in-
strument, or another effects unit).
* The unit's functions differ according to how it is
connected. Refer to "Connections" (p. 8).
* When running the unit on battery power, the
GUITAR IN and BASS IN jacks double as power

plug into the GUITAR IN or BASS IN jack; the
power is turned off when the cable is unplugged. Be
sure to disconnect any cord plugged into the GUITAR
IN or BASS IN jack when not using this effects
device. When the AC adaptor is used, the power
remains on at all times, and this function is disabled.
