Factory treble bleed circuit?

[RonB]

I'm having trouble determining what Gibson uses for treble bleed on its PCB control circuits. I ask because I've never had good luck with adding treble bleed circuits but the two Les Pauls I've had with circuit boards worked very nicely in this department. Does anyone know what value the cap is and is a resistor used with it? Looks to me like there's just a cap but that seems odd.  

Someone said 500pf with a 150K across it works best but there are a thousands of other combos that others swear by too. I have a Les Paul with classic PTP pots to which I would like to add whatever treble bleed parts are on those factory PCBs.

Thanks.
