The Blues Shaman emulates the tonal and dynamic range of a small Class A tube amp, with buttery warmth and soft clipping in its overdrive. This pedal gives you more of a power output stage overdrive which is very fat and full bodied. Its Ascension foot switch delivers feisty gain boost, and its Tone control shapes highs while retaining beefy lows. Further tone shaping comes by flipping the Stack/ Combo switch, which emphasizes tones characteristic of compact, open-backed amps or large-volume closed-back speaker stacks. You can also use the Stack mode to fatten up your Strat or combo mode to tighten up your Les Paul.
