CABLE CONNECTOR
1
This 7-pin DIN connector is provided for connecting the footswitch to the amplifier RE-
MOTE SWITCH (20) via the cable included in the carton. Connections at the switch and
the amplifier should be made before the amp is powered up.
LEAD/RHYTHM SELECTOR
2
This switch selects between the Rhythm and Lead channels on the amplifier. The adja-
cent LED will illuminate when the Lead/Lead channel is selected. When the LED is dark,
the Rhythm/Rhythm channel is selected. The CLEAN SELECTOR (32) must be in the
BYPASS mode to activate either the Rhythm or Lead channel.
CLEAN SELECTOR
3
This switch selects the Clean channel and will activate regardless of the position of the
Lead/Rhythm SELECTOR (31). The adjacent LED will illuminate when the Clean chan-
nel is selected. This switch must be in the BYPASS position, indicated by a dark LED, in
order to utilize the Lead/Rhythm SELECTOR (31).
EFFECTS SELECTOR
4
This switch activates the amplifier's effects loop. The adjacent LED will illuminate when
the effects loop is active.
