FRONT PANEL FEATURES
Input Jack – Designed to accept a standard ¼ inch mono phone plug. For
best results use a high quality shielded cable to connect your instrument to
the amplifier. The input is buffered and will handle standard passive, high
level active, and piezo input signals.
Gain Control – Regulates the first gain stage of the preamplifier and
controls the amount of signal available to the system.
Set Level Indicator – This light helps the user set the appropriate amount of
gain. When set properly, the indicator should light on your loudest/lowest
notes. We’ll go over this in more detail later in the manual.
Compressor Bypass Switch – This switch allows you to bypass the front
end Compressor/Limiter. The Compressor/Limiter in your unit is a fixed
threshold type. You adjust the Compression level by turning the gain control
up or down until you get the amount of compression you want. You may
find the bypass switch useful for getting that maximum punch when you are
slapping or popping hard.
Gain Boost Switch – Depressing this switch engages a +10dB boost. This
feature is useful for basses that have a low signal level. The light is on in the
High gain position.
Edge Control – Allows you to dial in as much or as little vintage tube style
distortion as you like. The control produces a warm single-sided, even order
harmonic distortion that sounds just like the old tube heads. With the control
turned fully counter-clockwise, the circuit is bypassed. The farther to the
right you turn the control the more distortion you will get. The distortion is
fairly subtle at low input levels and is more pronounced at high gain settings.
Enhance Control – Called the “Magic Knob” by some, this complex
control simultaneously boosts the very low bass, upper middle, and high
frequencies while putting a dip in the lower middle frequencies.
It is flat when set to its minimum level (fully counterclockwise).
