Finally, a word of caution: This method applies only to American made pots and not all potentiometer manufacturers subscribed to the EIA source code date.
But they did not use all MXR parts and the pedals are often not very well made.
Actually I'm trying to reconcile some inconsistencies with my early 1970's Jazz Bass.
I have owned this since 1990 and always believed it to be from 1971 or 1972. Or it is a 137 = CTS pot 35 = 35 the week , 2 = 1972Look there; // Info Your guitar was made at the Fullerton Plant (Fender - CBS Era), USAin the Year(s): 1971Some contradiction here but nothing unusual.
If the board is shown with some new looking foam on it, (to hide the actual board) that is another bad sign.
We don't have many old MXR pedals for sale (we dont deal with vintage gear much anymore) so we are not trying to sell you our pedals instead of these.
