My LTD M-100FM (1 vol, 1 tone, 3-way Strat switch) had a problem. Whenever I was on the bridge position the output/volume dropped a lot. I had to move the switch and play very hard to go back to normal on the bridge positon.

A luthier saw it once and said that it was the switch, not the pickups but he needed a new switch to change it. Now he want $10.000 pesos (around $20 US) to swap them.
That is way too much cash for that.

I bought a new switch yesterday (3-way too) but it's different to the original.

Here is the original.

Here is the new Ernie Ball 3-way Strat switch.

I don't know what i have to solder and where. The pickups are stock and aren't 4 conductor.

Can anybody help me? I tried to understand all the switching but i don't understand the diagrams.


I think you can figure out the other side from that. C means common, as in 1, 2, and 3 on that side connect to that when switched.

Actually you are a little off Mike. Usually, the numbering on the old switch goes:
123C C123

Just like the pic in the link Minnis posted.
