I needed a soft distortion pedal to do some dirty cleans (e.g.: Mastodon's The Hunter, The Sparrow, Thickening). That clean sound that has a bit of dirt in its end, that's how I interpret it...
I previously bought a Little Big Muff to that end, but I soon learned that it wasn't suitable for the sound I was looking for. I than used my amps heavy distortion soften with a volume pedal to cut the guitar signal. The sound was near what I envisioned but it lacked on presence and brightness.
I decided to get a non expensive overdrive pedal, that could get really soft and offer more EQ control than a single Tone knob. And I found this. After owning lots of EHx pedals (besides the Little Big Muff) I trusted the brand and I didn't get disappointed.
The distortion knob can go from very very subtil to very intense, without getting into fuzz territory. The volume pedal acts as expected, muting the pedal, compensating from the volume loss/increase of the distortion knob or really boosting the signal. The bass and Treble offer great tone shaping, they can really be boosted or cut, and bring some meds in in the process, and they are certainly more versatile than just a single Tone knob. However it would be perfect with a mid knob, and certainly easier to find the right sound.
I am very satisfied with the pedal, to those dirty cleans it is perfect, to some delay play (The Edge like) it make some notes crash beautifully and to spark a more subtil solo it is great!
