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
