I have an ESP LTD EC-1000 equipped with EMGs. It has 2 volume knobs and 1 tone knob...

I also have a Jackson Kelly that I customized and put Slash Alnico II Pro Pickups into...

I don't like the feel of the Jackson as much as I do the ESP, but the EMGs are just not really cutting it anymore for the music I play (they are a one-trick pony)...

So I was thinking about swapping one (or both) of the Alnicos into the ESP, but I'm not entirely sure, and would like some other guitarists opinions on the situation. Obviously if I swap them both out, the wiring stays relatively simply. But if I decide to do an active and a passive, what kind of things do I need to be aware of?

If I had my way, I'd crush your face in the door.
you can do that? i thought you could only do one or the other

I'm disgusted with the fact that Attack Attack can make money and a career by sucking so much dick.
EMG's faq section or the wiring thread could have given you the answer, but here's what EMG says about it:

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 fi ne. 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.

so basically..you CAN mix actives and passives, but really (IMO) it's usually easiest to just have an all active or all passive setup.

any more questions about mixing, just ask and I can try to clear anything up
If I keep my EMG in the bridge, and wire the Seymour Duncan into the bridge position... With my 3 way switch, could I make it?

Bridge Position - Mid Position - Neck Position
EMG Split SD Full SD

Is this absurdly complicated?
