CABLE CONNECTOR
This 7-pin DIN connector is provided for connecting the footswitch to the amplier RE-
MOTE SWITCH (20) via the cable included in the carton. Connections at the switch and
the amplier should be made before the amp is powered up.
LEAD/RHYTHM SELECTOR
This switch selects between the Rhythm and Lead channels on the amplier. 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
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
This switch activates the amplier’s effects loop. The adjacent LED will illuminate when
the effects loop is active.
