Btw, I loaded a pair of Duncan's in my 02 LP standard. (Bridge: JB, neck: SH-1 59) not sure what your experiences are, but being a volume control freak, I quickly noticed the Duncan's with the stock pots caused very steep roll off in volume, (10 to 7 was all she wrote) and drastic drop tone - this was a big deal for me. So after some research, I went about installing better pots (CTS long shaft 500k) and adding the Treble Bleed circuit (set at about past mid point for both pots) and this did the trick for me. The volume roll off is now far more gradual, (right down to 1~2 range where it cleans up nicely for rhythm and chord articulation) and the tonal characteristics are maintained through out. Total SCORE! [The JB bridge PUP is a concealed weapon!]
Anyway, just thought I'd add those 2 cents..

Thank you. I also replaced the stock pots with CTS 500k long-shaft pots and .047 capacitors and haven't had any problems. I did all this at the same time I replaced the pickups and tuning machines. And yes, that Duncan JB is a "concealed weapon"! The tone and sustain is great! Later I plan on replacing the stock bridge and tailpiece with probably a locking Tone Pros.

So yea, I wonder if Duncan pickups just wind up requiring these kind of components. My other LP Standard ('95 all stock 490/498) is great, only thing I had to do since I got it in 95, was replace the machine heads (installed same Gibby style heads it came with)

I don't know if the Duncan pickups require those componets or not. I've built two Warmoth guitars; one with a Duncan Distortion (bridge) and Duncan Jazz (neck) and the other with a Duncan Hot Rails (bridge) and Cool Rails (neck and middle)and have always used CTS 500k pots and .047 capacitors with great results. I have heard that 500k pots are better than the 250k for use with humbuckers though.

Agreed, 250k is typical for single coils, unless it's a p90, then 300ks are usually advised.
with HBs, I always have used 500k, I believe (but no way to confirm) the stock pots were also 500k, but they worked poorly with the Duncans, yet, no problems with the stock pickups. It was only till the pickup change out that I noticed the difference in response, btw the cap you have installed I believe will essentially do the same, where as the TB circuit lets you vary what gets thru and what gets filtered via a trim pot that comes with the circuit.
