61516: +) # (4 # ¶4· # &RQWURO
The ‘Q’ control varies the bandwidth of the EQ section in the range Q=1 to Q=3. A
low value of Q gives a wide bandwidth.
This means that a relatively large range of frequencies (either side of the centre fre-
quency selected by the ‘Frequency’ control) have boost/cut applied. As the value of
Q is increased, the bandwidth is reduced, so that a very much smaller range of fre-
quencies have boost/cut applied.

A dual-concentric potentiometer where the ‘inner’ knob is the ‘Boost/Cut’ control for
