Does what it says on the tin
Very versatile pedal. Can get very gnarly and aggressive, so remember to experiment with the Q knob in combination with the Blend Knob to tame the beast. Optional expression pedal turns it into a highly customisable wah-type effect. Even though this is the guitar version, it works surprisingly well on bass as long as you remember to blend in some dry signal. The pedal did seem to introduce a little noise into my signal on occasion but I can't be certain if this is inherent to the pedal or if is an effect being caused by a ground loop (I run direct input to my laptop) or the fact that my signal chain is so long.
