OK, a return to the x-140....

I can NOT figure out the wiring for the 3-way. Is it a DPDT switch? I'll try to draw a diagram... I would like to use the stock 3-way if possible. It's looking like that ain't gonna happen, though... So I'm thinking I'll replace it with a 'normal' 3-way, and a toggle to add the middle switch in series. No REAL problems there..

As for the nut, there is a local lutheir shop that has a bucket of old used brass nuts, and has offered to replace mine for $15 - $40 sight unseen

I think that's my best route, as the nut that came with this guitar is a) broken b) from an acoustic guitar and so would be pretty well useless for a template. Also I don't have any nut files.

Unless anyone can help with with either a source for a slotted brass nut that will fit, or at minimum the string spacing in mm, I think i'll take her in..

I can give you string spacing, let me dig up a metric ruler.

The 3-way is a standard guitar 3-way, which is not the same as a DPDT, it selects A or B ot both- so it's an On-On-On, but not the same as standard electronics On-On-Ons either (those are like a Mustang or Duosonic). They have three lugs, one for each pickup hot lead and one that goes to the volume pot.

You can get replacement 3-way switches at any guitar electronics supplier, or most likely from your local music store. The only thing to check is physical fit- there are some L-shaped 3-way switches used in Gibsons that won't fit in that space, you want the smaller more normal looking kind.

The 3-way in mine has 6 poles. And they are not redundant, as in the on/on/on in my t-60 with 6 poles, where adjacent poles are attached:

T-60

1------2---------to whereever

3------4---------to wherever

5------6---------to wherever


it's more like (not exact)

--1 2
/
/
3 4----

5------6----

or something similar; it REALLY looks like a DPDT.. I'm VERY familiar with wiring guitars, so I GUESS I'll just replace it with a standard guitar 3-way (I've got a gold one in stock SOMEWHERE) and an SPDT to get the middle pickup in series with the other two..

it does sound like someone put a DPDT in there. I just pulled the pickguard off an X140 and the 3-way has only three lugs.

But... I seem to remember having seen 3-way switches with six lugs like a DPDT, and only one side being used. I'd test it with a volt meter to make sure both side lugs are connected to the middle when the switch is in the middle position.

The 3-way with 6 lugs is the switch in the first diagram, same as came in my peavey t-60. I haven't cheked it with a multi (DUH!) but the wiring is just so jacked up, if it is in fact a 6 pole 3-way switch there is NO way it could posibally work the way it is wired...
