Up for sale here is this NOS NIB vintage IRC potentiometer, from the 1940s and Made in USA. This is a 250k ohm audio taper potentiometer with a loudness tap. It's a 250k ohm pot and tests around 296k ohms on my multimeter. This has a long shaft but you can cut it down if you want. This is guaranteed to work great for you, though it may need some Deoxit. This is probably too big for a guitar or bass guitar, but should fit in an amp just fine. Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All of my small parts are set up for combined shipping--just use the "add to cart" feature and then check out at once, and the shipping will be automatically discounted.

I have more potentiometers and other vintage electronics listed--feel free to take a look!
