1975 MXR Blue Box

This is a vintage 1975 MXR Blue Box fuzz octave guitar effects pedal. This particular “script logo” example is in pristine 100% original condition. This early version is not a “Bud” box example, though it does have both a script logo back plate and corresponding script logo graphics. It also includes vintage MXR rubber knob protectors and a fresh Indestructo cardboard box.
