This is essentially seven pedals in one: A TS-9 tube screamer, a Big Muff, a ProCo Rat, Metal Master, DOD 250 overdrive, MT-2 metal zone and DS-1 Distortion. Whilst they are not actually endorsed by their respective makers, these are the models that Digitech have based their settings on. This pedal allows you to tweak your distortion settings with three dual concentric tone knobs covering a three band EQ, level, mid boost and gain. You can achieve everything from a nice mid-range crunch to some proper shred tones, and you don’t need thousands of pedals on your board. Great for someone who is looking for their first distortion pedal, but can’t decide between the famous brands.
