what is the D type pot?

finally i get a cool fat strat scheme for my babe, but there's some D500K pots...
i know A and B difference, but whats the D type?
can i use A for it?

Pots are all basically the same thing. There are very minor changes in each that make them more specialized at something than others. A and B pots are most common becuase they are specialized pots. A pots are generally used as tone pots and B's are used as volume pots. They each do the specific task better than the other. However, D pots are more of a rarity. They're more of a "middle-of-the-road" pot. They're the multi purpose pots. They won't outperform an A pot as a tone pot but will as a volume pot. And vice-versa for the B pots. So, if the diagram has the D pot as tone pot, you can use an A... if it's a volume pot, you can use a B. I would recommend it that way anyway. 90% of guitar parts stores don't even carry D500k pots.

thanx! :D
it was a squier fat strat scheme...
and it has two D500K for tone. so first ill go with A pots, because i got tons of them already...

Sooo. I messed up my A pot, but found a d500k in an older guitar that was in my grandmother barn. Will an B pot be OK to use as tone and D pot use as volume since D pots are Universal?
