Gibson guitar potentiometer database
Find pots by guitar, or correct guitar model by partnumber
This Gibson pot database contains part numbers with respective models for all Gibsons from the early 1960s until the early 1980s as described in the various replacement parts lists distributed by Gibson.
As always with Gibson, there a probably many vintage guitars that don't conform to the catalogue descriptions, which are often incomplete and may even contain errors.
Gibson pots are NOT all the same. Most 60s-70s Gibson potentiometers were made by CTS (Chicago Telephone Company), although other manufacturers did also supply pots to Gibsom. Pots usually have several identification numbers. One is the manufacturers id code with date, and another is the Gibson part number. The manufacturers code has six (1950s) or seven digits, starting with 137 (CTS) or 134 (Centralab), and ending in format y/ww or yy/ww [where y is the year, and w is the week of the year]
Pots are marked on their backs or their sides.
Some models seem to conform to the part lists, some differ WIDELY. I have seen many seemingly-original pots with codes that do not follow the typical Gibson numbering, and many that just do not conform to the correct resistance values as described in the schematics. Gibson, no doubt, used parts that were available, and no doubt CTS and other pot supply companies shipped replacement parts from time to time. As with all Gibson rules, these should not be treated as absolute. If you want to discuss or add data provided here, please start a thread in the guitar repair section of the forum
