Bought an entire pedal board for a really good deal and now I'm parting it out! I got a guy locally who wants this but i need $$! I looked on an EH forum and found out how to date the pedal off of the serial number on the pot and I dated it to 1980. I BELIEVE I did it correctly but if I am wrong plz correct me! The serial number is 1378044. $150 Shipped! Thanks!
