Hi guys the volume pot in my p-bass broke, I bought an A250k pot to replace it, as the ebay guy said it was used for Volume, however when I took the scratchplate off I found out that B250k was originally used, so I contacted the guy again and asked him whether this one will be the right one http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260784780667 as you can see it is listed as a tone pot, and the guy said "some suppliers have a different oppinion on this matter but my supplier say that A for Vol and B for Tone" now I am completely lost and frustrated, I hope wise UG users will be able to help me, thanks

Listen to Jim.
Jim knows all and sees all.
(Although he still probably doesn't have a clue as to how cool a Jordan Bosstone is )

As for myself, I prefer Audio taper (A) for volume controls and B (Linear) for other types (Tone, etc.) Although my Strat has A pots for all. Works fine for me.
Read this link for pot info:

the "B" or "linear taper" pot rolls off the frequencies along a strait line. BUT they way our ears hear this is with a noticeable change in the first 10% or so, followed by about 80% of hardly noticeable change, followed by another 10% of noticeable change near the end

"A" or "audio taper" pots are made to compensate for this. The tapering is different at each end of the tapering spectrum, which to our ears sounds like the complete roll off from 100% to 0% is more "gradual" and "smooth"

That's the simplest way I can summarize it.

And it is really a matter of personal preference

Hope this helps
