DMS-1 The King's 4th Pitbull build

Note that the wire colours will vary depending on the actual pickup.

Hi Simon. the wires were like the ones in that photo.
The red and green were twisted and soldered together.

cheers, Mark.

[Simon Barden]

Yes, but the red and green could come from different coils compared to the pickups used in the diagram. Never assume anything with pickup wring!

So impatience gets the better of me again.
30 coats of Tru-Oil but still half a bottle to go...

So to the wiring test.
Neck pickup switch works in one position, but from the other two nothing but stony silence.
Bridge pickup works on all 3 but lower volume in centre and front position.


The fat lady has yet to arrive at the stage.

cheers, Mark.

Parallel and split options are always going to be lower output than full series humbucking.

As the switches and wiring for each switch should have been exactly the same, then I'd first suspect a dodgy switch or dodgy soldering.

A broken coil winding could also give you the same results so that you only get a sound in the parallel position. With a break, you won't get any sound in the series position and if the broken coil is the one selected by the split, then you'll no sound again. If the switch contacts all buzz out happily with a meter, then measure the resistance across the two coils and check you get a 3k-4k ohm reading for both coils. You'll really need to unsolder the wires from the switch to do that.

After that, there is a very small possibility that one pickup may have it's wire colours swapped, but you should be able to check this by comparing the underside of the two pickups. I can see from a photo that the green and red wires are connected to the same points, but can only see the black and white wire connections on one pickup.

Hi Simon. Actually they are not wired exactly the same.
I was experimenting with various differing schemes to see if I could peer through the technical thicket.

The act of tapping the pickup whilst it was plugged in was all I went by.
I knew when screwing the scratchplate into position that it was most likely coming off again very soon.
When I do take it apart again (hopefully) I'll have a better idea of what's working and what isn't.

Meanwhile I'm taking the time to try and get this set up.
Disappointed with the SCA 'Septone' clear. Despite the fortnight of Tru-Oiling the body, the neck is still sticky.
The standard SCA clear gloss is way better. Used it on the TL-R neck last week and it was almost instantly dry.

cheers, Mark.

Fixed a couple of issues...
Decided that the Bridge wiring was probably spot on so...
Wired up the Neck pickup the same...well it's a mirror of the bridge due to routing the wires.
edit: the yellow wire is actually white to make it legible for the diagram


Meanwhile the neck was so damned sticky that I decided to sand it back and refinish.
This is the stuff to avoid


This is the stuff to use


cheers, Mark.

I’ve seen the SCA clear mentioned before (I think Phrozin uses it). How does it compare with other finishes? How many coats do you give the neck?

How many coats do you give the neck?

With the standard SCA clear I did 3 coats.
Left it for a couple of hours and then put it back on the guitar.

Interesting about your experience with the Septone. That was my preferred rattle can lacquer before I moved on to a spray gun.

I usually get the standard SCA due to price. Trouble is turning up to SuperCheap to find that they don't have any on the shelf.

Decided to use the Septone as it was recommended here, so not impressed at all with it.
Since the Coronavirus, I've decided to order it online and do the 'click and collect'.

cheers, Mark.

Yeah I use it in all my builds I use it In rattle can and with there 2lt tin, my cupboard has about 8 cans of it and 15 2lt cans of clear, white, black I sware by it and it's cheap
