ROOTMASTER EVO II
USER GUIDE
Equalisation
This consists of bass, middle and treble controls with two more rotary
controls placed in-between. 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 amplifiers. This is done by leaving the 340hz
and 1.6Khz controls set in their centre positions and using only the bass,
middle and treble controls to alter the overall tone.
Secondly, if more control is required then the 340hz and 1.6Khz controls
can also be used to tailor the E.Q. In the regions between the main tone
controls. This provides a very versatile equalisation section, it is simple
to understand and operate, yet provides a wide degree of variation. It
retains the simplicity of a three control tone section but provides the
flexibility of a graphic equaliser.
Compression
Adding a small amount of compression gives a fat bottom end to the
sound and allows a greater volume of amplification to be used without
the playing peaks distorting the amplifiers output stage.
You will also find that this will add definition to your playing bringing
out notes within a run more clearly as it evens out the dynamics of your
playing. A large amount of compression can be used as an effect but it
will tend to reduce the dynamics in your playing to such an extent that the
volume of the note will be the same no matter how hard or soft you hit
the string. Compression also adds sustain to notes making them longer
before they die away.
