I'd start with a 50K and reduce value of pot till your amp starts to pick
up the output jack signal, then read the pot for the value ballpark.

Thanks.
That sounds about "right".
This is a very, very early pickup design.
Cutting edge at the time, involving a pair of horseshoe magnets.

I am probably just going to order a small assortment of pots (luckily,
it appears to be a 1/4" shaft variety...) One of them will be
"close enough". It's not about the dollars, it's about being able to
fix it next week when I'm up there again. Regardless, any pot is
going to better that what's in there now, but it'd be nice to get it
right.
