  • works on bass

    As reviewed by Matt Funk on 11/22/2010

    Ive tried a great deal of filters for the bass trying to get a good tone (dunlop bass wah, fm4, octavious squeezer, baseballs, ehx enigma, ehx micro qtron, etc etc etc). this one however has the low end retention while not having the screechy loud output many filters have. another key difference that sets this pedal apart is the use of a gain knob. this allows me to dial in the right amount of volume to play well with other pedals like a fuzz or an octave pedal. This is however no mu-tron but it is a close, budgeted way to attain a similar tone.
