1CABLE CONNECTOR

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.

2LEAD/RHYTHM SELECTOR

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.

3CLEAN 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).

4EFFECTS SELECTOR

This switch activates the amplifier’s effects loop. The adjacent LED will illuminate when the effects loop is active.
