Every once in a while somebody with unearth a warehouse stash of the old Ohmite or U.S. Allen-Bradleys. If you ever find a case of these:
JA1N200P504AA 500K Type J
You can buy a new car... :toothy12: They beat the topic to death over on the SGF, right now the best pot going is a 1,000,000-rotation 470K Dunlop "Hotpotz" from some wah application they're doing, you can still get them for $20, $25 a piece. A 25,000-rotation pot translates to about a week, but they do that damnable industry-standard 20% variation that means it may be a month, a day, or not at all. All you have to do is stick a multi-meter on some "good" CTS, rebranded Gibson or DiMarzio pots to see that 20% thing is treated as a license to steal.
The biggest problem is that various volume pedal housings were made around a certain pot, with a specific rotation. And if your volume pedal housing rotates even a few more degrees than your new, different replacement pot - it means that the full-off or full-on mechanical stop is WITHIN the pot. For five minutes or so, cause you just broke the bugger. And if the pot's range is any bit much larger - it either won't go full on, or full off. So all those beautiful old ShoBud and Fender volume pedals are pretty much pot murderers these days. And yes you can tap a setscrew or weld a new stop into one, thereby "ruining" valuable vintage equipment - that doesn't WORK... :dontknow: :icon_tongue:
I got a 24 watt powered Hilton five years ago or so, with a tone control and maximum and minimum volume controls on little screwpots on the bottom. The tone is identical from top to bottom, which I like. All that old "sweet spot" lore is based around the fact that's it's HARD to make the old stuff sound good, which is not a terribly useful way to get hired twice.
But lemme know FIRST if you unearth some "AA"-taper Ohmite "J" pots....

Addendum: I'm adding a link to a recent-ish SGF discussion:
http://bb.steelguitarforum.com/viewtopic.php?t=251371&postdays=0&postorder=asc&start=0
That's largely a discussion among amp makers, professionals and the Telonics, Mission and Hilton pedal manufacturers.
