DiMarzio Model J Installation - HELP!!!

The extra black and white wires per p/u are for a series option. For standard parallel wiring, solder the black wire to white wire for each p/u put some electrical tape on the solder joint and tuck the wires underneath the p/u, then, Red is hot (to 2nd leg of pot). Green is ground (to pot top).

David-
It makes sense to me that for parallel wiring tying the black and white wires on each p/u together to be closing the connection per p/u as opposed to running one p/u to the other. No?

If that's series wiring, how would you wire them for parallel?

 

Thanks for clarifying!

I find it strange that the DiMarzio instructions default is series wiring.

 

just checking out the thread(due to interest in the model J's myself), and it seems there's a bit of confusion with the series/parallel wiring options.
each of the j-pickups is humbucking and should individually wired in series, with the two pickups(bridge and neck) wired parallel like a standard jazz. hope that makes sense.
just my .02

 

Yeah, there is some confusion going on here. The difference is some of you are talking about wiring the pickups together, and some are talking about wiring the individual COILS of the pickups. The question he has involves wiring the pickups COILS together. As such, series is the standard wiring for DiMarzio pickups. To achieve this, follow the above instructions for each pickup. Following the "red = hot, green = ground" with each pickup, to the already existing volume pots, wires the pickups together in parallel, which is the standard wiring for Jazz basses. I recommend following these instructions to the T. You may later want to look at a series/parallel mod, which, at the flick of a switch, would allow the pickups to be wired together in series.

 

Just today I installed some Model J's into my Geddy Jazz. It really sounds great, but I wonder if I did it series or parallel. Here's what I did:

-Red wire of each pickup to the #2 post (hot) of each volume pot

-Green wire of each pickup were both soldered to the grounding screw that attaches to the plate at the bottom of the control cavity

-Black and white wires of each pickup were soldered together.

The only variation I did to the instructions that came with the pickups for series (humbucking) wiring is that I wired the green (ground) wires to a central grounding point, instead of to the back of each volume pot like it says in the directions. The reason why I did this is because that's the way the Geddy was originally wired, and all the grounds seemed to connect to this one location.

Can someone let me know where I stand? It sounds really good, tons of punch and a warmly aggressive personality with (thankfully) very little sheen or unnatural brightness.

Anyway, I'd just like to know if I wired everything properly for the tone with the maximum amount of "guts" and output, which I gather is known as "series", yes?

Thanks,
JMJ

 

You have it wired with the coils in each pickup in series, and the pickups in parallel with eachother. The grounding you have is fine, and possibly even better then the "standard" method, if done well.

 

Thanks, Dan. But is this method not the optimum amount of output or punch? In other words, since I have the pickups in parallel, shouldn't I get them so they are in series?
Best,
JMJ
