Many musicians, including Metallica's Robert Trujillo and Primus' Les Claypool, have used MXR products. (Titles omitted)
This is an octaver pedal for bass.
This model is also known to be a favorite of Kazuki Arai (King Gnu) and Derrick Hodge. (Titles omitted)
In addition to mixing the original sound and the effect sound, the Growl control adjusts the mid-range of the octave sound, and the Girth control adjusts the depth and smoothness.
You could say these two controls are the EQ for the octave sound.
There are scratches and dirt, and the pedal shows signs of use overall. It works well.
