Strat HSS with two Tone pots and P-Rail SHPR-1

[eric.se]

:newbie: I cannot find anywhere on the web how to connect my new SHPR-1 to my Fat strat which has:
- 2 tones
- 1 volume
- a 5-way selector
- 2 single coils (middle + neck)

With two tone pots, it is complicated :banghead: to understand which wire goes where... it's very confusing really.

to chose between sounds, I plan to replace the pots by push/pull ones.

I would really appreciate your help :help:

Thank you
Eric
:eek2:

Swap the push pull wiring in that diagram for this one:

Re: Strat HSS with two Tone pots and P-Rail SHPR-1

I appreciate your help.

However it looks straightforward to you, it's not for me.

Indeed on the 2nd diagram, the two push/pull are both on the volumes pots, obviously one for each SHPR-1. and a 3-ways toggle is used to select the SHPR-1 internal coil combination (rail, P90, Humbuck serie and parallel) as far as I understand.

This is not the setup I am loking forward to implement: I wish I can use the 2 push/pulls the enable any of the 4 possible combinations:
* rail only
* P90 only
* P90 + rail in serie
* P90 + rail in parallel

Hence I need to place one push/pull on the volume pot and the 2nd push/pull on either of the two tones. So far I didn't find any wriring diagram showing that, even on Seymour Duncan support site (which looks awesome)

(note that the two push/pull can also be on the two tones if this is feasible, I bloody don't care where they're as long as they do what I want...)

I wish you could give more light.

Thanks
cheers
Eric

Re: Strat HSS with two Tone pots and P-Rail SHPR-1

I've finally understood how to install a SHPR-1.

However I'm stuck with integrating with the original wiring of my Fat Strat:
The original wiring uses the humbucker in series and connects the central point of the humbucker to the 5-ways switch to disable one coil in a given position:

This setup is the exact original, hence uses Fender color convention for the humbucker (see vendors color convention)

So I've decided not to connect this middle point. Here is the final wiring I did:

It works (only in position 1 on the 5-way switch) but the difference is very very very subtile: the two tones set to zero with slight distortion, I can hear that the series position is more loud than the others

I'm afraid I've screwed something, can someone tell me what?

Cheers lads!

All you want from this diagram is how to wire the push/pull switches for the bridge P-Rail. That's it. Ignore the Neck P-Rail and any other wires in that diagram.

Take the black wire that goes to the volume pot in that diagram and wire it like the black wire for the bridge pickup in this diagram, and wire everything else in this diagram exactly as shown:

Alternatively you can put the P-Rail on a TripleShot and get what you're after, and it's easier to wire up.

Re: Strat HSS with two Tone pots and P-Rail SHPR-1

Thank you for the help.

I understand that my HSS was in autosplit mode, which automatically shortcuts the south coil of the humbucker in position 4, to avoid having 3 coils, hence a better hum cancellation, but the wiring is more complicated.

Thanks to the push/pull, I can do this manually, myself, hence use a more simple wiring (the first you proposed).

I understand everything now

Re: Strat HSS with two Tone pots and P-Rail SHPR-1

The following mod enable selecting standard pickup combination plus almost all possible pickup combinations such as neck + P90!

To that aim the p-rail is always-on but is controlled via two push-pull switches.
I've wired as a normal strat and connected the p-rail black wire to the common pin of the 5 ways switch so that the p-rail is always present, whatever the 5-ways switch position. The common pin is easy to pick-up: it has a wire from the 5-ways selector to the 5-ways selector itself (on another pin of course).

Then implement the following push-pull wiring which enables selecting either:
- the rail (when tone 1 is up, tone 2 is down)
- the P90 (when tone 1 is down, tone 2 is up)
- the humbucker in serie (when both are up)
- disconnect the p-rail (when both are down)

(be careful that one of the push-pull on the drawing is up-side down as it would when actually wired on the pick-guard. the blue is not meaningful)

It works like a charm enjoy new Gibson like sounds on your strat :scared:

Re: Strat HSS with two Tone pots and P-Rail SHPR-1

Could you help me too?
I have seen these diagrams before and many diagrams similar to what I want. However because I am a wiring novice I nedd something a little more closer.
I have a tele with a Prail mounted in the middle, a 6 way 2 pole rotary, 1 Volume and 1 tone.

How would i wire the guitar so I get:
1 Neck tele
2 neck and bridge tele
3 Bridge Tele
4 Rail
5 P90
6 PRails Series - Dp switch to Parrallel.

I figure it wouldnt be to hard as it is standard tele then 1 humbuckker guitar wired to the same volume and tones

Oh yeah, the Volume and tone are both push pull pots if this makes it easier though I would like to avoide push pull functions as it is time consuming to do whilst playing a roaring solo.
