This is an extremely straight forward pedal. There are four controls which can be manipulated; treble, bass, volume and gain-- basically your standard Overdrive pedal settings.
This pedal gives you so much options (boost, crunch, regular OD, soft-hard clipping mode, EQ) that you'll find your thing, while the character of your guitar stays intact. The thing that makes this pedal stand out is the ability to choose what side to stack.
The BB Preamp by Xotic Effects is a warm sounding true bypass distortion and sustain pedal that is very easy to use. It has four knobs built into it: Gain, volume, treble, and bass.
