bout the taper, it doesnt go by brand, but more on whether is it a log pot or linear pot.
just need to find out before buying, whether its a A or B stamped on the pot. If dont have, heh, just buy and use mutimeter to figure out. Both will work for geetar, although if wanna follow strightly, log pot for vol and linear for tone. Reasons why can be googled thru searching for "potentiometer, secret life of potentiometer" etc.
gotoh, allparts usually will have such indication on it. Just need to look at the right place. Usually theres indication either at the base of the pot or stamped letter and value on the pot.
