Using this as my main overdrive and distortion pedal on one of my ampless pedalboard setups, with a Friedman IR-X at the end.
Incredibly versatile and allows for (or requires, depending on your preferences) a lot of experimenting with tone and the two different gain stages. The EQ faders are very useful for detailed tone sculpting, and even when the Fault V2 is set up for heavy duty distortion - which it does remarkably well! - your guitar strings are beautifully represented and detailed. As a "milder" overdrive, pushing an already driven sound just a bit more, I find it delivers equally good. It does thick/creamy and bright/screamy and pretty much everything in between, without ever sounding boring.
If you want something very simple, or are already set for your preferred tone, this might not be for you. If you don't mind fiddling around a bit, as the different dials, faders and switches interact quite a lot, this pedal can shoulder the burden of many different overdrives and stretches well into distorted rock territory. Although it took me some hours to wrap my head around all the interactions, this has quickly become my favourite overdrive pedal. At least so far. :)
