The Diablo is a versatile low to medium gain overdrive with an exceptionally dynamic response.
It preserves the character of your instruments and is very sensitive to your playing technique.
Thanks to the effective and musical controls, the Diablo works equally well with any kind of guitar,
amp or playing style. People use it for so many different sounds, you would hardly believe
that they use the same pedal.
Besides the usual Gain, Tone and Level knobs, the Diablo has some more interesting controls:
FEED affects the amount of bass in the input signal. You know the problem: an overdrive sound
gets muddy rapidly if the input signal is too bass heavy (that’s why the treble booster was invented).
With the FEED control you can make even the fattest neck humbucker sound clear
and transparent or beef up weak pickups a little.
The BODY control takes effect on mids and compression.
Another important feature is the HEADROOM SWITCH. Set to the "HI" position,
an internal electronic voltage doubler is activated – the Diablo runs on 18 Volts
from a regular 9 V battery or power supply.
The higher voltage gives more dynamic range, more headroom and
tighter bass – just try it!

For complete specifications and description of all the controls
please check the user manual (PDF).


The Diablo comes in two versions: the regular one
and the Diablo Gain+ with two footswitchable gain settings
(sounds are the same in both versions).

A lot of user videos can be found on Youtube.
I recommend to check out those made by Gregor Hilden
for great blues tones (and some very nice guitars)
or a variety of other clips.
Here’s two of my favorites with Les Paul and Strat - thanks Brett!
