What is that jumper for? Does that connect hot leads of bridge and neck together? Wouldn't that just make it always on in parallel?

It's a series middle pup blending pot mod...

Rock_on

Anyone please? So i could start wiring?

The mod does more than just blend the middle pickup in series with the other two.
In positions 1 and 5 in blends the middle in series with the neck or bridge.
in Position 3 the blend pot does nothing.
in position 2 the pot blends between middle and bridge in parallel and middle and neck out of phase in parallel, that's what the green jumper on the switch is for, it reverses the polarity of the neck pickup.
Position 4 is like position 2 only the other way round it blends in bridge out of phase that's what the brown jumper on the switch is for.

Wooh, gee thanks... now it's clear. I step back a bit and paused while wiring when I saw that. I got puzzled.

But, how does that reverses the phase? When the jumper does connects the hot leads of neck and bridge? Isn't that parallel connection like position 2 and 4? or like the neck/bridge parallel blend mod?

slacker

Which jumper are you talking about? The one's on the switch don't connect the hot leads of neck and bridge.

Here's a drawing of how a Strat 5 way switch works http://3.bp.blogspot.com/_8pKbeWMtBCs/TUBDS6WBQPI/AAAAAAAAAQw/kU8dBqvW0R8/s1600/5waySW.png the mod drawing is using the standard version. See if you can use that understand what the mod does.

That looks pretty cool but what if you only want bridge pu or neck pu all by itself with no middle pu blended in? Personally, I could not live without those options. I have a push/pull tone pot to turn my neck pu on/off and that's good enough for me... for now  :)

Hmm weird, I don't know if I really understand how it works or what...

I can't really understand why it does not connect the leads.

Left side 1 goes out to the right side's 1 also and the same with 2 and 3. C is always there, hence the name.

I know it works how I described it that's why they put tone knobs on the same number... because they are identical. So instead of having 3 wires in 1 hole, they put it like that.

Am I right or wrong? Cause if not, that's how I understand it for years.

I see why you're getting confused, the left and right sides are not connected, see the picture I posted. There might be other sorts of Strat switch which work how you said.

With the blend pot turned all the way down there's no blending and you have the normal Strat pickup selections. The only difference is the tone is rewired as a master tone.

I looked at it for the millionth  time (not really)... I still see it that way

Edit:

I googled it for some info. I get now a bit, it's just like 2 switches working at the same time. The switch would work like how I describe it if the two common is jumpered.

Mine does not even need jumper (I guess), cause when I was troubleshooting i touched each holes (remember I have the import type 2) with a wire to see if they are working connections..  and it worked! Without jumpering both Cs.

Now explain how does that wiring work or atleast how did it reverse the phase?

Rock_on

Ok, I put an effort to read the explanations on how the 5 way switch works.

On this mod, what is the sense of using the right stage, 2nd bank, or the other side when the common 2 is not even used?

I undestand that when on position one, lug 1 on both sides goes to the common of both sides.

You can wire tone controls on the other side but you need to jumper both common (mine does not work like that tho)

I'm really confused, and someone (let's just assume to those who would also read it in the future) from strat-talk wants an explanation too

Rock_on

Finally! Someone's explained it very well!

The bottom pot is a series blend. It sends the bridge and neck ground wires EITHER to ground on the back of the pot (normal strat sounds) OR to the hot wire on the middle pickup. That puts the pickups in series in positions 1 and 5. 

But the really clever thing are those red and blue jumpers. They ground out the hot lead of the UNSELECTED pickup in positions 2 and 4 (Example: in position 2 bridge/middle parallel, the blue jumper connects the NECK pickup hot wire to ground). This does nothing . . . UNTIL you turn the bottom pot which blends those pickups in parallel and out-of-phase because the ground wire of the UNSELECTED pickups gets blended into the signal while the hot lead is grounded.

So anyway: with the bottom pot fully down you get the 5 stock strat sounds. 

But with the blend pot full up you get:
1. Bridge+Middle in series
2. Middle||Neck parallel out-of-phase (Bridge - both leads are shorted together so not in the signal)
3. Middle
4. Middle||Bridge parallel out-of-phase (Neck - both leads are shorted together so not in the signal)
5. Neck+Middle in series

How can I do this wiring with this kind of switch? It's the only available kind of switch locally.



Can I just scrape the connection with an x-acto knife?

slacker

Does the switch work the same as import 2 shown here? http://3.bp.blogspot.com/_8pKbeWMtBCs/TUBDS6WBQPI/AAAAAAAAAQw/kU8dBqvW0R8/s1600/5waySW.png

If it does then you just need to cut the connection between the two commons.
