About 30 years ago I had an Electro-Harmonix Talking Pedal - a combination vocal formant/auto wah/distortion pedal for guitar that sounded amazing.
The pedal swept between A E I O and U vowel sounds, and the distortion tone was deadly. With the right settings & footwork you could make mind-bending guitar "speeches" in Martian!
I contacted EH a few years ago to ask if it would ever be re-issued, but they said they couldn't because a dual-shaft potentiometer used in it's construction was no longer available from the manufacturer.
The recently issued Talking Machine pedal is a pale shadow of the Talking Pedal, and doesn't even begin to replicate the mind-blowing sonics of the original.
I want to see the original Talking Pedal re-issued, in both guitar and bass versions.
