The Top cut is also a stepped switch control. It acts in the
same way as the Bass cut control. Positions 1 to 3 give a
6dB / octave low pass filter that decreases in frequency as
the control is increased. Positions 4 to 6 give a shelving
filter that acts lower in frequency the more the control is
increased.
2.3 Stereo Width Section
This section of the Fat Bustard is concerned with adjusting
and tailoring the width of stereo with respect to frequency.
Some features here are very similar to those found in
Elliptical equalisers, most often found in mastering
applications. Specifically vinyl mastering and cutting.
2.4 Stereo Spread
This control can increase the apparent width of stereo at
full bandwidth, or frequencies above a selected point
ascertained by the Bandwidth control. As the Spread
control is increased the stereo width increases from normal
to very exaggerated.
There is an On/Off switch located next to the Spread
control. This takes the Spread in and out of circuit.
2.5 Bandwidth
This control is a stepped switch. At the bottom position the
spread can be increased across all frequencies. Then the
next positions give a high pass filter function to the spread
at frequencies 100Hz, 250Hz, and 3kHz respectively. This
effectively means that at maximum (3kHz) the spread
affects higher frequencies only.
2.6 Bass to centre
This control is a switched step control. At the bottom
position (Full) the stereo is unaffected. At the next position
up frequencies below 100Hz are made Mono whilst
