I'm digging the Duncan SS4s.  Duncan specifies 250K pots for both volume and tone.  That's what I got since that's what they were designed to use.  Braided wire not necessary IMO.

Usually you use a 500k for tone and 250k for volume if you're going to use 500k at all.

I went 500k for both vol and tone with the Lull pup.  I thought about the 250 but why give up any treble if only one pup version...  I would not change a thing as it sounds huge.....

500 vs 250 for the tone pot - If you run it wide open, does it make a difference, or does pot value only effect the amount of roll off?

Stewmac has a good article on which tone pot to use.  Reading it, it does seem to make sense to use 500K for vol and tone on a humbucker.  I'm going to give them a try.  Says it does make a diff, wide open or not.

Good article!

No harm in erring on the side of a high value tone pot.  You can still sweep the 0-250K range, and with it set in the higher resistance values >250K, it just means that less high frequencies are being bled off thru the cap to ground.

Unless you use a switch to bypass the pot, or one of those "no load" pots (takes itself out of the circuit when its full "open"), there will always be some signal (high frequencies) getting bled off.  Whether or not its perceptible depends on the ears involved  :)

Thanks guys. I knew I would probably get something wrong. Spilt shafts it is.
