GUITAR RETURN Jack
This is an input jack for
connecting another effects
device, electric guitar, or
other instrument.
When connected to this
jack, you can use sounds
other than the normal
pickup when Master is off,
and for the Mix sounds
when Master is on.
(refer to p.11, 12)
OUTPUT Jack
This jack is for connection to a guitar
amp, another effects processor.
* The OUTPUT jack also doubles
as the power switch when the
unit is running on battery
power. The power comes on
when a plug is inserted into the
INPUT jack, and goes off when
it is unplugged. Unplug any
connected cords when the unit
is not in use.
AC ADAPTOR Jack
This jack is for connecting an
AC adapter (BOSS PSA-series,
sold separately).
Using an AC adapter makes
possible long performances
with no worry about batteries
going dead.
GK IN Connector
This connector is for connecting
your guitar with a GK cable.
NORMAL PU MIX Switch
When Master is on, this switch determines
whether or not the normal pickup sounds (or the
sounds input to the GUITAR RETURN) are mixed.
By mixing the normal pickup sound,
you can create a sound that makes
your guitar sound come alive.
GUITAR OUT Jack
Normal pickup signals input
through the GK-2A are output.
When a cable is
connected to this jack,
the output of the
normal pickup from the
OUTPUT jack stops.
