Wiring up MM pickup to blend?

[TheFunktopus]

Is this possible? Wiring up each coil to a blend knob? This diagram shows a MM wired with 2 volumes, so a blend should be possible, right?

I want to do this in my MTD Kingston Artist, can anybody identify/label each wire coming from the pickup? Green, white, red, black, bare. The yellow taped wire is coming from the pickup. The green and white are twisted together and taped, not wired up to the preamp at all. Image is attached.

I don't know your particular bass, but what you've got appears to be a dual coil that is hard-wired to a series configuration. Some testing with a multimeter would tell the tale.

1. Separate the spliced wires
2. Test for continuity between red, black, green, and white to figure out which wires go to a common coil.

If your pickup had the coils hard-wired parallel, you'd have two wires going to the positive side of the circuit and two to the negative. Since you've got two spliced and not connected to the circuit otherwise, this indicates series wiring.

Using a blend pot is possible, but it will require the coils to be in a parallel configuration. Since your pickup is currently hard-wired in series, it was most likely designed with this configuration in mind, and will probably not sound terribly good and will have a volume drop in parallel or with either coil soloed.

But... as long as you're careful and don't damage anything, it costs nearly nothing to try and see how it sounds. Just leave all your wires at their current length - don't cut, just de-solder - so you can return to the stock setup if you want.

It's possible, but not very practical. What do you hope to gain by doing it?

I'm a cheapskate and wanted to use an Audere preamp I had lying around (designed for 2 p/u instruments) instead of purchasing a new one.

I think if you get yourself an asymmetrical wound humbucker it might be cool. If you have matched coil windings there wouldn't be much of a difference between the two. However something like the Dual Resonance pickups from Dimarzio have different resonance peaks on each coil so the difference might be more noticeable if you use the slug coil vs. the screw coil.
