USER GUIDE
ABM EVO IV
A Mix of these two amplication sections can be achieved with this
control.
N.B. The degree of tube distortion provided by this control will also depend on the setting of the
INPUT control.
VALVE DRIVE IN/OUT - This push button switches the valve drive section
IN or OUT. This function may also be controlled from the Ashdown 4 way
footswitch. For the footswitch to operate this button must be in its OUT
position.
E.Q. IN / OUT - This push button switches the Equalisation section IN or
OUT i.e. the Bass, Middle and Treble controls plus the two sets of sliders
placed between each of these.
This function may also be controlled from the Ashdown 4 way footswitch.
For the footswitch to operate this button must be in its OUT position.
9 BAND EQUALISATION - This consists of BASS, MIDDLE and TREBLE
controls with three sliders placed between each control. This can be used
in a number of ways:
Firstly as a very simple Bass, Middle and Treble tone control section as
found on older traditional ampliers. This is done by leaving the two sets
of sliders interposed between these controls set in their centre positions
and using only the BASS, MIDDLE and TREBLE controls to alter the overall
tone.
