Contour
- The contour cont
rol is an active wide band sweep. In the 12 o’clock position, the
amps’ frequency response is flat. Counterclockwise rotation reduces high end response and
increases low frequencies. Counterclockwise rotation decreases low end and increases the high
frequency response. This control is very useful for maintaining preamp tone control settings, while
allowing a global adjustment to compensate for differences in room acoustics, speaker cabinets,
or bright to dark guitars (PRS Humbucker to Strat, for example). This control also actively reduces
the articulation available, allowing a softer setting or extremely open and revealing, depending on
your individual style and requirements.
Rear Panel Functions
1.
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.
2.
Fuse
- See Fuse Chart
3.
Power Switch
- Turns power on.
4
. 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
impedance of your cabinet with the impedance (output) of the amplifier.
5.
Return Level
- This control has a pull-bright function. The loop is active in the circuit even with no effects
connected, so the level control acts as a master volume. The pull-bright feature is useful when playing at
low volume (a low fx control setting) or when a large number of outboard effects are used in the loop, which
sometimes causes high frequency insertion loss.
6.
Effects Send
- Use this jack to send the amplifiers signal to outboard effects.
7
. Effects Return
- Use this jack to connect the output of your effects to the amplifier.
8.
Pickup Loading
- This control has 5 settings. In the first position (fully counterclockwise), there is no
additional pickup loading, with 4 additional settings available. Fully clockwise (last position) is full loading.
Loading the guitar pickup(s) to varying degrees changes the impedance relationship between the pickup
and the amplifier’s first gain stage. Loading reduces inductive “ringing” in the pickup coils. The effect is a
more controlled high frequency response and a reduction in high frequency artifacts produced when a
pickup’s magnets and coils feed back with each other, usually at or near the pickup’s saturation point. The
damping effect will also reduce the gain, which is normal. Tonally speaking, reducing these artifacts results
in a cleaner waveform and an apparent lack of harshness in the upper frequencies.
