Ok, you know me... maybe not. Anyhooow. Now that this axe is blazingly good, I am wondering if, as suggested long ago by newey, I can get some other goodies going with my circuit ala DPDT instead of the two neck only positions on that DPDT when thrown to the series mode. So given what I have is there a simple add on.... i.e, a switchable cap, that would give me some other options. While I quite like all the tones on this rig, perhaps a slightly brighter version of the Middle pickup for instance might be useful. I also do not have all three is parallel?? I don't suppose that can be achieved in this config? Essentially, here is what I built. There is no shielding ( save that which is on the P90 via VV ) on this rig yet..... and it is remarkably quiet. I will be going for a pick-guard shield at some point, but since its a hollow structure I do not think I will be going for extensive Faraday cages here.  |

And:
And, you just finished it. Yet, you want to pull it apart again already for further modification?
Yes, we know you. You're a Guitar Nut! ;D ;D
If you look back through your original post, I recall that ChrisK has already given you an idea for using a "special cap". While you ultimately didn't use his design, you can probably incorporate something similar into your existing design.

I think there are some options for squeezing a bit more juice out of those parts. First a question - it looks like the + side of the P90 is directed towards ground - is that intentional?
Next, to get some more action, you can free up half the switch poles. The right side of the 5-way is not being used, so the white, hot wire to the volume control could go straight to the left pole, and delete the yellow wire between poles. Also, on the DPDT, the black and red wires from the pickups always end up being connected together, either to the white or the green wires. So both of those can be connected together to one pole and do those functions just with just one half of the DPDT.
So that frees up a pole of the 5-way and a pole of the DPDT. You also have available, the third lug of the tone control, which at max treble, is connected to hot.
So things you could add, 2 options:
1. This is the bridge version of Chris' "free neck on" module. Put a wire from the 3rd tone pot lug to the bridge hot (ie the one that goes to the 5-way, black in the diagram but should it be red?). This will force the bridge on in parallel, when at max treble and so would give you N+B and N+B+M options in parallel mode. If the tone pot is audio taper, then a very small turn from 10 down to 9 or 9.5 will revert to normality. This option did not need the pole changes described first.
2. Or, In series mode, tone controls can become very interesting if at max treble, they bypass the neck pup with a cap. The result is, at 0 tone, the treble is fully muted as usual, it is restored as you turn up (as usual), then, as you approach 10, the neck gets bypassed by the cap and there is an easier route for the treble from the M and B to get through, resulting in a brighter tone at max treble, but still with the weight of bass from the neck. I have this on my Strat Dual sound design and it is also the Red Rhodes module of Chris. You can do that here, but use the free 5-way pole to make it happen only with the 5-way in positions 4 and 5. Without doing that, you get a quirky dull neck sound with max treble in the neck only positions 1 and 2.
Neither of these need new parts
If you were adding a switch, a DPDT phase switch on the neck is good fun.
What do you reckon?

I reckon that the first mod sounds like my deal. Now, does that retain the connections described in the diagram, and add those that you have delineated?? I will post a graphic to confirm the wiring ok..... thanks

Yes I think you can keep everything you have (Im still curious about the P90 red and black though), and just add one wire from the disused tone lug to the B connection on the 5-way

So, if I have this correctly, with this extra wire I will get B+N when the 5way is at the Neck position ( 1) with the DPDT on parallel ( standard ). And I will get N+B+M at the #2 position on the 5 way switch with DPDT on parallel. By backing off the tone slightly both positions revert to normal operation. see below I have changed out the P90 red wire to white and added the yellow wire as described. So things you could add, 2 options: 1. This is the bridge version of Chris' "free neck on" module. Put a wire from the 3rd tone pot lug to the bridge hot (ie the one that goes to the 5-way, black in the diagram but should it be red?). This will force the bridge on in parallel, when at max treble and so would give you N+B and N+B+M options in parallel mode. If the tone pot is audio taper, then a very small turn from 10 down to 9 or 9.5 will revert to normality. This option did not need the pole changes described first.  |

yes, I think that does it!
