This is an original 70’s Electro Harmonix fx pedal.
Great funky sounds, similar to a wah wah, responds to picking strength.
It is in very good condition, a few scratches to the top, exceptional for a 30 year old pedal. It is very quiet in operation, no crackles on the pot, in bypass it still enhances your sound!? You can tell its an original because it has no LED, the new re-issues do.
