See the note that says 300K after 7-1-73.
That doesn't specify whether it applies to volume, tone or both, and it doesn't specify linear or audio taper, but a look at later schematics confirms that the 300K was used for the volume pots, and the 300K Gibson has always sold as a replacement is linear taper.
Yeah, I saw them there at twice what I paid for them before. Guess I'll have to get used to the higher prices.
