More P-rail questions

I've been reading thread after thread after thread. I'm installing 2 P-rails in my les paul. I have my wiring diagram all figured out with a 3 way switch. Series/parallel, 50's wiring and independent volumes. And before you say it, no im not doing triple shots. Haha. I've wired/soldered guitars before but it's been a while and I just want to make sure before I start this project. I've never done push/pull pots or P-rails but I hear good things about both, especially together.

My only questions are:

1. What type of pots, dpdt or spst? I'm doing 2 regular volume pots and 2 push/pull tone pots. However I'm not sure if i need dpdt or spst for my pots.

2. Will a 3 way switch be good or should I use a freeway switch or something different? I would like to mess around with as many sound options as I can, with out any compromising.

3. What problems might I encounter with P-rails and my set up and how could I address them?

Thanks for helping out in advance.

Hi Marcay22, and welcome to the forum!

You say you have a diagram all figured out, so if you could post it that would make answering your questions much easier.

At this point the only question I can answer is that your push/pull pots will be DPDT... in fact I’ve never seen any other option.
 
Re: More P-rail questions

Okay, so you have a diagram that will allow you choose series or parallel for each of the P-Rails. One of the most attractive things about P-Rails is their ability to have 4 distinct sounds: series, parallel, P-90, and rail. Your diagram will give you access to 2 of the 4 sounds. If that’s all you’re after then you’re good to go. Otherwise you’ll need to do something different if you want access to the other two sounds.

So the question becomes “What do you WANT it to do?”
 
Re: More P-rail questions

I would like all 4 sounds please. How would I go about doing that. With similar wiring hopefully.

This should get you there:

The only thing this won't do is allow you to have the two pickups in different modes from one another, but it's a fairly simple wiring job. If you need more options than this you will need to start adding 3-way mini switches which will mean drilling holes in your LP... OR (and I know you said you didn't want to) use Triple Shot rings.
 
Re: More P-rail questions

Ahhh. Ok. I see. But that removes the independent volumes and 50's wiring style doesn't it?

Btw thanks for the quick responses. I expected to get answer tomorrow.

Oops... forgot about those! [emoji33]

You can still do the 50s wiring and independent volumes. Just wire the pots themselves like your original diagram, but wire the two switches like the one I gave you. [emoji41]

One other thing in terms of what problems, I had one of my PRails internally out of phase with itself out of the box, and have heard of it from others (though fairly rare) - search way back on my name and PRails, I did a long post with a fix update.
