Seymour Duncan JB and 250K Pot

[Grumpy]

Question: I've got a vintage 2 wire cream "The JB Model" SD pup and have read that some players use a 250K pot to smooth the highs. Anyone have real world experience with this set up? Did you notice a difference compared to running a 500K pot?

I'm putting the pup in a northern ash body, with quarter sawn maple neck, single hum Charvel with original brass bridge. Thanks Vince

I have 500K pots on my two JB guitars, and with the tone knob dimed, is a nice well-balanced tone. You can always roll it off a bit with a 500K, but with a 250K you might be limited.

Yes is does tame down the JB and you will need to do that with the ash body and brass bridge.My 85 ESP has a 320k RSguitarworks super pot and its is just right.

My 2005 SL2H has a 250K tone, but I can't make out what the volume is. My guess is that it's 250K also.

Here's an idea if you put in a 500K and don't like it - turn down the volume

a pickup wired to a 500k vol and 500k tone is yielding the same load as being hooked up to only a 250k volume pot.

Seymour Duncan himself runs the JB with 250k. The JB has a mid-spike and can be a little bright and harsh in some guitars with 500k.

Wouldn't it be the other way around? It's been a long time since high-school physics class, but don't you add resistances in a series circuit?

from what i've read, the standard duncan wiring scheme for 1vol 1tone is wired in parrallel. so 2x500k loads in parallel would equal 250k total. like how 2x16ohm cabs = an 8ohm load on the head... same principle.

of course they're parallel.
