    Is there any way to see when my electro harmonix pedal was made? (In this case a poly chorus)

    If it’s a vintage one (non-stereo), you can look at the back of the pots. There’s a 7 digit number that starts w/ 137. The next 2 numbers are year and the last 2 are week. That actually tells when the pot was made but can be a fairly good indication of when the pedal was made, too.

    If it’s a newer stereo unit there’s no numbers that I’m aware of.

    thats pretty neat, is there any meaning for the 137?

    137 is the manufacturer code. In this case, it’s CTS.

    Holy Mackeral!

    About 15 years ago I rescued a Small Stone and Electric Mistress from a neighbor’s carport. (He just gave’em to me. They were in his CARPORT. In Hawaii… ugh)

    Anyhow, back then I didn’t know squat about guitar pedals, I just held onto them and used them for recording, etc. I assumed they’d been made in the late 80’s/early 90’s or something.

    After checking this forum in a fit of curiosity I just looked under the hood and the Small Stone is a ’78, the Electric Mistress is a ’77.

    Thanks friendly neighbor dude. :thumb:

    Great pedals, great years in EHX history, and all of history for that matter. Congrats on your lucky score.
