Up for sale here is this NOS NIB vintage Mallory U53 1 meg ohm audio taper potentiometer. This tested right around 1.05 meg ohms. It is undated but is from the 1960s and is Made in USA. This has a long round 1/4" round shaft, but you could cut the shaft down to use this in a guitar. The pot body will fit in a guitar just fine. This has an open space in the back of the body to mount a power switch, but you can just ignore that if you want. This is guaranteed to work great for you, though it may need a little Deoxit. Please see my pictures for details and measurements.
