Dating cts pots richard gutierrez kc concepcion dating
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.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 you see a NOS MXR pedal, ask about the date codes, and try to get a picture of the inside to see if it's original.The source dating code is an element of standardization that is administered by the Electronics Industries Alliance (EIA).The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits). At least now we know that the Mistress can not be older than the pot. Unfortunately now we know only the manufacturing date of the pot and not the Mistress.
137 stands for the manufacturer code, 77 is the year und 18 is the week.
