Two-Rock Custom Reverb - Rear Panel Functions; A;C Input; Fuse; Power Switch

A/C Input- Connects the amplifier to A/C power via the power cord supplied. Unless otherwise
specified, your amplifier is designed to operate on 120 volts A/C, 60 cycles.
Fuse- 3 AG Type, slow blow fuse. 50 Watt amps use 2.5 Amp slo-blo; 100 Watt amps use 3.5 Amp
slo-blo.
Power Switch- Turns power on.
Ground Switch- Normally left in the center “off” position. If you encounter excessive AC hum or
ground loop noise, try the switch in the other two positions.
Speaker Output Jacks- There are 3 speaker output jacks; 4,8, and 16 ohms. NEVER OPERATE
YOUR AMPLIFIER WITHOUT A PROPER SPEAKER LOAD CONNECTED. Be sure to match the
impedence of your cabinet with the impedence (output) of the amplifier.
Footswitch Jack- The footswitch connects here. The clean/lead and tone bypass functions can only be
activated via the footswitch.
Effects Send- Use this jack to send the amplifiers signal to outboard effects.
Effects Return- Use this jack to connect the output of your effects to the amplifier.
Effects Level- Adjusts the return signal level. It also acts as a master volume control. Do not set fully
counter clockwise, as this will shut off signal to the output section, resulting in no output level. Nor-
mally this control should be set at the 12 o’clock position.
Feedback Switch- This switch defeats the internal feedback circuit located in the preamp section. The
effect is subtle. You will notice a slight increase in high and low frequency response and a decrease in
dimensionality and articulation.
S/N- Your serial number is located here. We strongly suggest that you record this number and have it
handy in case you need service, or in the event that your amp is lost, stolen, or damaged.
