The PRE EQ (EXPERT) function is available in all presets—regardless of which configuration is currently
recalled.
This function allows you to shape the tone prior to the distortion stage. Considerable tone variations can be
achieved by modifying these pre-distort EQ parameters.
The PARAMETER SELECT control will allow you to access these PRE EQ parameters:
The pre-LF (low frequency) LEVEL parameter allows you to cut or boost the low frequen-
cies from -15dB to +6dB prior to the distortion stage. This EQ section is a shelving-type.
The pre-LF (low frequency) FREQUENCY parameter allows you to select a frequency
band with an upper frequency between 63Hz and 500Hz to be cut or boosted by the pre-
LF LEVEL parameter.
The pre-MID LEVEL parameter allows you to cut or boost the mid-band frequencies from
-15dB to +12dB prior to the distortion stage.
The pre-MID FREQUENCY parameter allows you to select a mid-band center frequency
between 500Hz and 4KHz to be cut or boosted via the pre-MID LEVEL parameter.
The pre-MID BANDWIDTH parameter determines how wide or narrow the bandwidth of
the selected mid-band frequency is (in octaves). A small bandwidth only boosts or cuts
frequencies close to the center frequency, while a large bandwidth affects the level of
frequencies up to two octaves from the center frequency.
