The Evolution Orange Underdrive
(EOU) offers a new way to
approach your tone. instead of
overdriving your clean tone, now
you can get cleaner tones from
your favorite overdriven tone.
The EOU works really well with vintage
single channel amps that sound great
when you push them to overdrive.
When you turn down the volume from
your guitar to clean up that tone, the
sound often gets a bit too dark and the
clean tones are not as desired as the
overdriven tone.
With the EOU you can tailor your
cleaner tone with the four pots.
The Evolution Orange Underdrive
works by lowering the midrange as
that’s where the overdrive mostly
happens.
You can dampen the amplifier input with
the EOU’s Volume control and then set
the Bass and Treble to tailor your clean
tone. The EOU can also be used to
boost the mids by settings the Midrange
and Volume up.
HOW TO USE IT:
Set up the EOU before a distorting
amplifier or pedal and set your Volume
at about 12 o’clock and Midrange to 9
o’clock, then turn the Bass and Treble
for the desired bottom and brilliance.
After that re-adjust your Midrange and
Volume to taste.
NOTE!
The Evolution Orange Underdrive is not
meant to produce a pristine clean sound
out of a distorted sound, but to make
a less distorted sound with impressive
punch and brilliance.
