Up for sale here is this used vintage CTS 50k ohm potentiometer, dated 1962 and Made in USA. This tests around 40k ohms on my multimeter. This is an odd pot--it has a very limited travel, just 180 degrees, instead of the usual 300 degrees. It is some sort of audio taper, I think, but I don't know for sure. At the halfway point it tests around 10k ohms.

This has a short 1/4" D shaft, so any standard D shaft knob will fit it, as should any 1/4" hole knob. This is guaranteed to work great for you, though it may need some Deoxit. This is a pretty rare potentiometer and would be great on your guitar or amp. Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
