Up for your consideration is an EXCELLENT, clean and fully functional example of a late 60's / early 70's Maestro WW-2 "Wha Wha Volume" pedal. The original box is here and worn (see photos). The pedal itself is very very clean. The only non-original part is one black screw on the battery compartment door. This has a really unique and amazing sounding sweep to the wah sound! Very different from a Crybaby or any other of the familiar ones out there. It gets guttural at the bottom/heel position and super sweet on the top end of the treadle travel. Don't miss this one! You might never find one again... I package my items with care and ship them out quickly. Thanks for looking and have a great day!
