Tone capacitors with P-Rails?

I'm about to put a pair of P-Rails into one of my guitars, with the Triple Shot rings. I figured while I was at it, I'd replace the pots with CTS (500k). Also, I want to change the 47k capacitors that are in there.

I was reading some recommendations for 22k caps with P-Rails and 500k pots. But I have a pair of Russian oil-based 33k pots that I read were a good match for P90's, and I am tempted to try those out.

Also, is there a recommended sequence for replacing all this stuff, after I've got the old electronics desoldered and pulled? Like wiring caps to pots first, then triple shot to pots, then pickusp to triple shot or maybe a totally different order? I can see myself halfway through realizing too late that it would have been easier to wire things up in a different order.

I love the .022uF with my neck/Rhythm position P-Rails. I sometimes wish for a different value on the bridge/Treble position P-Rails Hot but one Tone pot is all that the host guitar has.
 
Re: Tone capacitors with P-Rails?

First of all, it is important to understand the values of pots and caps so there is no misunderstanding on your part or ours.

Pots come in several main values listed as resistance (ohms)...250k ohms, 300-330k ohms, 500k ohms, and 1meg ohms. The "k" equals 1 thousand.

Caps for use in guitar tone circuits are listed as "uf" (micro farads) and sometimes/rarely as "pf" (pico farads). The most common values are .047uf, .022uf, .015uf, .010uf.

You mentioned that you have..."a pair of Russian oil-based 33k pots". Those do not exist, there is no such thing. (You may be referring to paper-in-oil .033uf caps?

In any case, I would recommend .022uf caps and 500k pots (audio taper)nfor use with P-Rails. But, if the caps you already have are .033uf, I would just use those and see how you like it before buying anything else.

I like .022uf's also, but have occasionally used a .033 with good results, when I was out of .022's.
