Vintage 1973 Maestro ME-1 Envelope Modifier Filter Missing Back Plate 1970's ME1

Description

This listing is for a Vintage Maestro Envelope Filter Electric Guitar Effect Pedal. This is a very interesting Maestro pedal from 1973. The pedal takes some time get used to and dial in the settings correctly. It’s a little similar to an EHX attack decay. It works better on single notes than chords and doesn’t track as fast as you would hope but it can still make some unusual phases and sounds. There is also a percussive and a bowed attacked effect and if set correctly can also even get a reversed tape effect. The pedal shows heavy cosmetic condition and is missing the back plate nevertheless the pedal functions as it should. The potentiometers have a date code of the 6th week of 1973. The pedal comes as shown with no additional items. Please look carefully at the pictures and email with questions.
Thanks for looking!
