Maestro MPF-1 Parametric Filter 1977 s/n MPF1970 in very good condition including the very sought after battery cover.. and in full working order. The Maestro MPF-1 Parametric Filter designed by Bob Moog for Norlin/Gibson 1970's.
You can boost or cut your sound up to 20db and send frequencies flying on any one of five total settings, three of which are clean, and the other two all nice and fuzzy.
The Maestro Parametric Filter is a clever, clunky filter pedal that a resourceful player could use for everything from simple EQ to total fuzzification of their signal. It was part of the Total Foot Control series of pedals which were designed to play the knobs and switches with your feet.
This pedal is used by Alex Lifeson of Rush as well as Joshua Homme of Queens Of The Stone Age.
