I'm looking to add an octave pedal, and have narrowed it down to the MXR M288 Bass Octave Deluxe & the MXR Sub Octave Bass Fuzz. I already have a Wampler LowBlow Overdrive/Distortion, so I don't know if the Sub Octave bass Fuzz will be redundant. There seems to be great reviews and adherents for both pedals. Opinions? Thanks!
