Just got this baby in the mail about an hour ago. I absolutely love it. I'm sure most of you know all about this pedal already, but I thought I'd share my thoughts. Controls are pretty basic: Gain, Volume, Bass, and Treble are self explanatory. The bias is almost a voltage starve. All the way down and you get some sputtery gated tones, all the way up you have sustain for days and some harmonic overtones with the gain up. This thing is so versatile. It does everything from a mild grit to full on fuzz. I prefer it in the middle though. It has a nice chunky distortion with the gain between 1 and 3 o clock and the bias just below noon. Like I said, though, I've only had an hour with it. I have a Rusty Box as an always on preamp/tone shaper, and the Mini almost feels like an extension of it. Now I can dial the gain back a bit on the Rusty and have almost a clean tone, and use the Mini for my grit. This is subject to change, though, depending on how practice goes. The bass on this thing is crazy. No low end loss at all. In fact, it can get bassier with the Mini than without. A first for me, after spending the last year with the disappointing Bass Big Muff Pi. If I didn't need the Mini as my standard-ish OD, I would crank the gain and bias and kick the BBM to the curb. I got the top mounted jacks and it had a different design. Nice surprise! Everyone should have one of these.
