Several years ago I found a thread that suggested installing a metal film resistor across 2 terminals of a volume control pot to improve the signal's clarity. IIRC the idea was that much of the signal would then pass through the installed metal film resistor, and still allow the original volume pot to function, thereby bypassing some of original carbon volume pot's likely muddy performance . I can't find the posting now. What terms should I search for ? If this mod is valid, what resistor value should I try to use with a 100K pot ? Thanks for direction and advice. The amp is a 1960's Kenwood 1100U; basically a Japanese Fisher 500.
It depends what your definition of 'clarity' is.
All a resistor will do is either turn a linear tracking pot into a log pot or antilog pot, making the volume level more or less at any given point.
Unless the resistor loads the pot in which case it will reduce the pot's impedance giving a change in characteristics of the driver circuit. Possibly reducing bass response maybe.

The term you should search for is 'audiophile nonsense'.
If a pot has a poor quality resistive track then you get best performance from it by not loading it, not by increasing the load on it i.e. that advice is the direct opposite of the truth. If you are worried either use a better pot or add a buffer immediately after it.

meaningless babble showing muddy brain instead, based on an unfounded belief that "metal is more expensive so higher quality, carbon is cheaper so lower quality"
Similar to "silver is more expensive than copper, so wiring my amp with solder wire will make it sound better" and tons of other similar ones.
Best case we should define clarity and muddy and then do some measurements and blind tests to check whether resistive material choice actually modifies them in any perceptible way.
A resistor used with a potentiometer is usually to make a Log type out of a linear potentiometer. The search term I would use for this application would be 'law faking resistor'
Linear Pots are usually more accurate than log types which can improve the accuracy of stereo balance.
The disadvantage of a law faking resistor is that the resistance that the driving stage sees will vary which might not suit your application.

I'm sure if You wire a 1 Ohm resistor along the pot, it will pass ~100000% of the "clarity", but if will also increase the input sensitivity, and then You have to pad it down with some more "clarity" resistors ….Wake Up !!
