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!
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).

I bought this pedal after a few really good video demos and some good online reviews. While the pedal sounds pretty decent, I can't get past the fact that it sounds like a blanket has been put over the amp. The only other pedal I've had that did the same was a cheap $50 pedal. You can somewhat help it with an EQ, but you shouldn't need to with a pedal at this price. Mine is going back.
