This output is switchable between pre-EQ and post-EQ signals using the adjacent push-
button switch.
Speaker Output(s) - This jack is the speaker output jack for connecting to a speaker
cabinet. For the mono model, this output would normally be connected to the internal
speaker in the cabinet. The amp delivers 75 Watts into 8 ohms and 100 Watts into 4
ohms.
Fuses - The main line fuse is a 5A/250V Slo-Blo for 120V & 100V use, and a 2.5A/250V
Slo-Blo for 220V and 240V use. To reduce risk of fire, replace fuse only with same
type, as specified.
Setting Up for Optimal Performance
A simple step-by-step procedure is outlined below for setting up the amplifier for optimal
performance.
1. Reset Controls - Turn the power on, turn down the instrument input & master
volume, set EQ flat, and turn notch control all the way clockwise (no cut).
2. Set Input Level - Plug guitar into instrument input, and turn up the input volume until
the green LED is on most of the time and the red LED only lights occasionally on the
loudest notes.
3. Set Tone - Turn the master volume up to low listening level and set the EQ &
contour switch to taste.
4. Eliminate Feedback - Mute the strings with your right hand by the bridge. Turn up
the instrument volume until the guitar almost, but not quite, breaks into feedback. Now
tap the soundboard with your finger on your right hand while continuing to mute the
strings, and you should hear a "ping". Set the notch-filter depth control at 12:00. Now
slowly rotate the notch frequency control from about 12:00 to 5:00. At some point the
"ping" should disappear and you'll just hear a dull "thunk" every time you tap the top.
Now the notch filter is tuned to the soundboard resonance of your guitar. Now bring the
master volume up to playing volume. If you get a low rumble or roar when you try to
turn up, push the phase button next to the graphic EQ on the channel you're using, to
cancel the air cavity resonance. The correct phase depends on the position and
