I'd go with a 250k linear taper volume pot, a 250k audio taper tone pot, and a 250k M/N taper blend pot (M/N is the taper best for a blend pot), with a .047μf cap, or a .022μf (slightly brighter) cap. I ground the casing on all pots, but I do not ground the lugs on the blend pot ( just leave them open), (it gives a more usable sweep, and more open sound), though most diagrams show the lugs on the blend pot grounded (there isn't a need to). Linear pots , for me, work better as volume pots, but , not for tone, (audio is better for tone). This info puts a damper on buying a pre-made set of 3 pots, but, it sounds best to me, for V/B/T.
