8. Master Volume Control
This controls the overall volume of your amplifier. Use in conjunction with the volume control to
find the perfect balance between pre/power amp distortion and output volume.
9. Dark Switch
This switch allows you to further tweak your amps tonal diversity. When the Dark switch is
engaged, the high frequencies are dramatically cut. This makes the amp feel like a completely
different beast!
10. Power Switch
This is the ON/OFF switch for the power to the amplifier. Please ensure the amplifier is switched
off and unplugged before being moved.

1. Output Jacks
This is where you can hook up an extension or external speaker
cabinet(s) if desired.
EXTENSION SP: This speaker jack runs parallel with the internal
speakers which are wired for 16 Ohms. The extension cabinet must
be 16 Ohms.
EXTERNAL SP: This speaker jack will mute (disconnect) the
internal speakers and you can hook up either a 16 Ohm or 8 Ohm
cabinet. Be sure to set the Output Select switch accordingly.
NOTE! Hooking up a cabinet through the External jack will mute (disconnect) the internal speak-
ers!
WARNING! To ensure that your system works correctly, you must observe the following points.
a) Don't use an extension cabinet whose impedance is other than 16 ohms.
b) Don't connect a speaker whose rated input capacity is less than 18 Watts. The speaker may
be destroyed if you ignore this caution—not recommended!
c) You must use a speaker cable to connect an external speaker. Don't use a shielded cable like
the one you use to connect a guitar to an amp.
d) You must turn off the power before connecting the cable. Connecting the cable while the
power is turned on may damage your amp.
2. IMPEDANCE Select Switch
16 OHMS: Combos allow for the following configurations;
• Set it to this if you use the internal speakers only.
• Set it to this if you connect an external 16 Ohm speaker cabinet through the External jack.
8 OHMS: Combos allow for the following configurations;
• Set it to this if you connect an extension cabinet through the Extension jack. You'll be run-
ning the internal and external speakers in parallel. The impedance of the extension cabinet
must be 16 Ohms.
• Set it to this if you connect an external 8 ohm speaker cabinet through the External jack.
