I purchased these from Stewart McDonald , these are 500 K Gibson true historic pots. I wanted to compare to a standard CTS log pot that I typically use and these historic pots are also CTS. I always use 50’s wiring in all my guitars. One of the things I didn’t mention in the video is that none of these were 500K. They were within the 10 percent tolerance. Here were the readings. 545K 538K. 535K 532K. All checked at an ambient temp of 76 degrees.
