I assume it's possible to have an original 'parallel/OMG' bass K-modded to 'parallel/OMG/single'? I think I've only seen K mods discussed on instruments with the now standard series/parallel options

I'm pretty sure my very early L1000 switches parallel/single coil/OMG.I assume it's possible to have an original 'parallel/OMG' bass K-modded to 'parallel/OMG/single'? I think I've only seen K mods discussed on instruments with the now standard series/parallel options
It is possible, you need the 3-way switch and need to do some re-wiring. Back when mine was built, the K option didn't exist. I believe it was standard on the Japan-export basses and word got around, users wanted it in the States and it became an option…at least that's the story I heard…I assume it's possible to have an original 'parallel/OMG' bass K-modded to 'parallel/OMG/single'?

I'm surprised that the early L's had parallel and OMG. Are you certain of that or have documentation to that effect?
Huh...just found a posting by the late-lamented @Chef who said the following with reference to his '81 L-2000:
"The E-series have a very cool difference from current production L2000's in that the coil tap has, dual coil, and single coil with bass boost instead of dual coil series, and dual coil parallel. This lets you get much closer to "standard J and P" tones. You can dial this in (or out) further by adjusting either the pickup body, or pole pieces in the single coil side: sweet."
That's different than OMG which is series with a capacitor on one of the coils.![]()
Series doesn't sound good by itself in my opinion.
But in terms of cutting through a dense mix, I've never run into anything that does it with the consistency and power that series does.
It's not even close.
I've tried this with my '81 L-2000 and it behaves the same as your Wunkay in OMG mode. Both coils on but one of them noticeably quieter when tapped with a screwdriver.If I put my Wunkay into OMG mode and tap the pole pieces of the pickup with a little screwdriver, it's clearly both coils on and one of them with a lot of high frequency content removed (presumably by the capacitor).
Maybe @ped you could do the same thing with your bass and see if the OMG setting has both coils on or, as @Chef suggested, it's only one coil and that one with the high frequency rolloff.
I'd be very interested to find out.
Here is a link with a page from the early manual for L-1000 and L-2000 E basses. For both basses it refers to the OMG mode position as single-coil with increased bass. I think this is a bit of a misnomer, but maybe they went with that terminology because that mode with the coils imbalanced allows for hum to be introduced, like a single-coil.It's absolutely possible with a 3-way switch and a bit of wiring ambition. When you do the k-mod on a new L-series, the existing parallel-series switch is entirely removed and replaced with the 3-way, so the same could be done with yours.

On mine (sold last year), the red switch selected between "humbucking" mode or "single coil" mode where "... an increase in bass ratio is provided." I've always assumed that's what you all mean by OMG mode. (And it sure was sweet...)Here is a link with a page from the early manual for L-1000 and L-2000 E basses.

Exactly the same.It's actually the same I think,

Oooh I saw this in the local Craigslist this morning! Ebony board, right? It did raise my eyebrow...I have a killer Kiloton V that I'd trade for a JB5 !!!View attachment 4413434
