I need to know how to wire up 2 humbuckers (1 Passive/1 Active) with a 3 way toggle, 2 volume, and 2 tone controls. Also possibly adding a killswitch. Anyone know how to run this properly?

I know there is a output difference but it doesnt matter for what I'm doing.

From EMG's support page:

Q: Can I mix EMG's with passive pickups?

It is possible to mix EMG's with passive pickups. There are three possible wiring configurations; one is better than the other two.

Use the high impedance (250K-500K) volume and tone controls. The problem is that the high impedance controls act more like a switch to the EMG's. The passive pickups, however, will work fine. If you have a guitar with two pickups and two volume pots, with a three-way switch, there is another alternative. Use the 25K pots for the EMG, and the 250K pots for the passive pickup. This way you can use one or the other with no adverse affects, but with the switch in the middle position the passive pickup will have reduced gain and response.

Use the low-impedance (25K) volume and tone controls provided with the EMG's. The problem here is that the passive pickups will suffer a reduction in gain and loss of high-frequency response.

This is the best alternative. Install an EMG-PA-2 on the passive pickups. There are two benefits to doing this. With the trimpot on the PA-2, you can adjust the gain of the passive pickups to match the EMG's. The PA-2 acts as an impedance matching device so you can use the low-impedance EMG controls (25K) without affecting the tone of the passive pickups. You will also be able to use other EMG accessory circuits such as the SPC, RPC, EXB, EXG, etc. For this application, we recommend ordering the PA-2 without the switch for easy installation on the inside of a guitar.

Appreciate it. I've read this before and know there is a difference because I used to have this wired up before and it was amazing besides the toggle switch making noise due to the impedance difference but now I'm not worrying about that since I have a JCM 600 which I can EQ the 2 channels seperatly.

I just need a diagram of how to wire this all correctly.

Follow this: http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_2v_2t_3w

And sub in EMG's recommended tone and volume pot values for the active pickup.

For a kill switch you want to add a SPST momentary switch on the line that goes from the 3-way to the hot tip on the jack.

ok ya that's how I've been wiring it up so far. Not done yet (shoule be tonight) but I was wrong about the killswitch so I'll rewire that. Thanks

Actually, an SPST wired between the tip and ring on the jack. It prevents that “disconnected cable� sound.
