Pots for guitars?

[mshuptar]

Hey everybody - this is a total noob question, but are guitar pots supposed to be audio taper or linear taper or both? Here's my situation: I got a crappy LP Jr copy at a yard sale. The knobs of the pots had been broken clean off. The values are as follows:

Guitar #1: "Talent LP Jr"
Volume: 500kA
Tone: 500kB

I was going to swap out the pots with some from another junkyard guitar (a First Act single-pickup model) and the pots in this guitar were:

Guitar #2: "First Act 5008"
Volume: 500kB
Tone: 500kA

So, here are my questions: Which pots were in the right place? Does it really matter?

General rule, linear for volume, log for tone, but you can go in any combination depending on your playing style.  I've got a Strat wired with a log pot for volume, you can pull off pretty cool stutter effects with a volume swell technique, but there ain't a lot of play in the sweep for cleaning up your tone subtlely.

Much appreciated - thanks!
