Hi there,

I've just installed a SD 59 SH-1n (2 wire) in the neck and a SD Vintage Stack STK-T3b (5 wire) in the bridge of my partscaster. I've got an out of phase switch located between the vol & tone pots and have the bridge pickup wired to switch the phase, using the wiring diagram at the Seymour Duncan website.

The problem I have is there seems to be no appreciable difference when the switch is in one position or the other, just a very slight change in tone. No volume drop, no nasal tone - nuttin'.

What's going on here? Can anyone shed anylight on the matter please?

All input is gratefully appreciated.

Regards,
Hoodie

P.S. The bridge pup has a brass baseplate if that helps

Check your wiring again......Hard to say without hearing it...Good luck...Cheers

Isn't your bridge pup a vertical humbucker design? Hence the name "stack"...

Switching the wires won't make any change (I think).

A dumb/obvious question first then some insight:

I assume you are trying the phase switch when the pup selector switch is in the middle position right?

I added a phase switch to a tele and decided to connect the phase switch to a 2-wire bridge pup. It didn't work and acted like a kill switch. Did a little research and realized the ground to the brass plate would have to be resoldered in reverse. Said to self "Self, forget the bridge" and proceeded to rewire to the 5-wire neck bucker. All was nasally after that. It doesn't matter which pick-up you phase to get the desired sound so I recommend the 5-wire neck pup on your guitar.

Yes it is a vertical stack. But I am trying to put it out of phase with the other pickup. Would being a stack make a difference?

Correct. I understand the basic principle of it so I am aware that the 3-way switch need to be in the middle position.

Thta's what I'd read here when researching, so that's what I did.

Yeah, what he said.

Jim.Collins · February 9th, 2009, 06:35 PM

Which diagram did you use?

HoodieMcFoodie · February 9th, 2009, 07:24 PM

OK.

This one came with the SH1-n

This one came with the STK-T3b

So I used the phase switching bit from the first one, assuming that the wire colours meant the same thing on both pups...

Jim.Collins · February 9th, 2009, 08:32 PM

So the bridge pickup's red and white leads are soldered together, and that joint is taped off. The black and green leads go to the DPDT switch. (The bare lead goes there, as well, but it is permanently tied to ground.) From the DPDT switch, there are two output leads. One goes to the selector switch and the other goes to ground. As long as the DPDT switch is wired correctly, this should work, and you should hear a significant difference when both pickups are selected.

HoodieMcFoodie · February 9th, 2009, 09:03 PM

Yep, that's exactly how I've done it.

I'll double check it tonight when I get home, but I'm 99.5% sure I've got it right.

Unless I've cooked the switch during soldering, but them it wouldn't work at all, right?

HoodieMcFoodie · February 10th, 2009, 08:42 AM

I had a look at it, but it seems to be wired OK.

I guess I'll replace the switch with a new one and see if that makes any difference...

Here's hoping.

I think you may be right udimet. Today I took the old switch out. I thought I might have cooked it during the build. I put in a brand new DPDT switch, wired it up, checked it and guess what? It still sounds the same.

I think I'm gonna try a SD Antiquity II bridge pickup. 2 wire jobby. Surely I can get that to reverse phase.
