Help with wiring trembucker and super 2 distortion in ST-1

Hi, i have built the ST-1.
I have bought a seymour duncan trembucker TB-59 tb, and a diamazio super 2 distortion to replace the pickups
and also have bought a 3 way blade switch to replace the 5 way.

What i wanted to do it was take the the existing 1 volume and only 1 of the tone knobs and wire all this together , i have looked at a few sites and they are all fairly different and as i have never wired a guitar id thought id ask for help.

From what i can find out with the trembucker red and white get taped off together, black goes to switch and green and bare get soldered on the back of the volume pot like in this diagram below

In regards to the switch the one in the diagram has 4 terminals on each side where as mine has 8 on one side and im not sure how to wire this (please see pic)

For the super 2 black and white get taped off together, green and bare go to ground and red goes to switch (i think) i could only find this page which is a bit confusing

Would anyone be able to tell me if this is correct and how to wire the switch .

Thanks Mark

I cant seem to get a image to upload but this is the 3 way switch http:/https://www.ebay.com.au/itm/Hi...72.m2749.l2649

You've probably got a photo that's too large, so you'll need to resize it. No bigger than 1500 pixels on the longest side. Windows 10's default photo viewer has resizing as a right-click option. Choose custom size and whatever's the biggest dimension, type in 1500 pixels. There's also around a 1Mb size limit, but this isn't normally a problem, but if it is, just use a higher compression ratio/lower quality setting on the slider when saving. Otherwise use an external image hosting site and link to it using the image button. (Note that the default upload and host locally tick box needs to be cleared if the picture is bigger than the forum upload limits). A maximum width of 800 pixels seems to be best for fitting a remote hosted picture on the screen.

Your 3-way blade switch is equivalent to the one in the SD drawing, except that the terminals on one side have been moved round so that they are now in a line. The two middle terminals are the common terminals for each 'side' of the switch.

You'll find that in the SD picture, the pickup signal wires are taken to the common terminals of each side. So in your case, taking the '3-way switch' text in the SD pic as the nearest the neck end of the switch (just imagine it's 8 pins in a row, not 4+4) and the top pin as pin 1, you'd solder the bridge pickup signal wire to pin 4, the neck pickup signal wire to pin 5, and link pins 1,2 7 and 8 together and out to the volume pot. Pickup grounds get soldered to the back of the volume pot or the tone pot. So it's basically the same as the SD diagram, but with a different topographic arrangement.

What the SD diagram doesn't show is that the backs of the volume and tone pots need a soldered link between them or the circuit won't work.

As you have noted, for the SD 59, the signal wire is black and the green and screen wires get soldered to ground. For the DiMarzio, the signal wire is red and the green and screen wires get soldered to ground. The remaining pairs of wires are probably already soldered and taped together.

Thats great info , thankyou for clarifying that for me.

In regards to the link between the volume and tone pots, do i run the connecting wire from the solder points on the back of each pot where the grounds would be soldered?
And also on the SD diagram it shows a black line/wire connecting the two pots via there terminals, i imagine this is something different ?
And if so does that black line/wire need to be soldered aswell.

Thanks again

I put an arrow where the wire is. I imagine that one is to tell the switch to operate both volume and tone ,where as the link your talking about is to complete the circuit? .

Also do i have to run the main ground wire to the bridge plate? or can i run it to where the spring on a humbucker screw sits , as the underside of my pick guard is shielded?

It doesn't matter where on the back of the pots you run the linking ground wire. You could even run another wire from the output jack ground to the back of the volume pot, just as long as there's a connection to ground.

I tend to spread out the ground connections of the back of the pots rather than have them all in one location as it's a lot easier to keep one wire in place than three of four when you've only got two hands available and you've got to hold soldering iron, solder and the wires.

That arrowed black wire is the signal connection to the tone pot. It's not a ground connection, so you still need to link the back of the two pots (added grey line):

The bridge ground on a Strat with a trem normally gets soldered to the trem spring claw. An example on this page: https://www.stewmac.com/Hardware_and...hoCC80QAvD_BwE

Excellent thankyou, much appreciated.

I was just looking at the wiring that came from the factory and was thinking i can unsold-er all the pick up and second tone pot wires,and wire the new pickups and switch in to save hassle.
Looking at it i can see the link wire (red arrows in pic) , but not a signal connection between the two pots, is this because its a 3 pot setup etc?
Do i run a wire like i have drawn in orange (orange wire goes from bottom terminal on vol to bottom terminal on tone, not connected to back of pot)

Thanks once again

The signal link wire in this instance is the green one to one tone pot and the blue wire to the other tone pot. The selector switch has a different configuration to the type of switch shown in the SD drawing. This one has three inputs for the pickups (the yellow, red and white wires on the right of the switch) and three output connections that are all connected together on the circuit board on the switch (the green, blue and red wires on the left of the switch). It makes it easier/quicker for the factory to wire using that type of switch.

The yellow wire you've highlighted with the orange is one of the interconnecting ground wires. There are two more (black) ground wires soldered to the back of the volume pot, one of which goes to the output jack, the other to the trem claw.

I always use black wires for grounds, and then any other colour for signal wires which avoids any confusion.

You could unsolder all the wires, but you've now got two humbuckers, so you've presumably got a new scratchplate for them, you've got a new switch, and you'll want new pots, as the current ones will be 250k and for humbuckers you'll want 500k pots. The tone capacitors supplied with the kit are probably 0.047uF ones, and for humbuckers, the standard is normally 0.022uF.

So the only item you can really re-use from the kit is the output jack and the scratchplate screws.
