A few months ago I received an ESP EC 1000 (amber sunburst model with Seymour Duncan pickups). However, I wanted a bridge pickup with more bite to it, so I bought and installed an EMG 81 in the bridge position. So now I have the EMG in the bridge and the SD 59 in the neck. While the EMG is active, the SD is not, will this cause any loss of tone? It isn't splitting the gain between the two, only letting the EMG reaching half its potential, is it?

The guitar works fine now, but the sound from the bridge pickup is indistinguishable from the sound from the neck. I think the wiring added some tone to the neck one in addition to the bridge.
That's odd. I heard that bridge and neck pickups won't work if they're on simultaneously, due to impedance differences.

in fact, that might be it: the EMG isn't working to its full potential, so you can barely hear it, while the neck pickup works fine.

Did you install a different set of pots for the EMG pickup?
i don't know the specifics of this, but i tried doing the same thing to my ESP a while back and i was informed that in order to have both a passive and active pickup in the same guitar you need to have a separate circuit of some sort, so either someone really good needs to install it for you or you can do what i did and buy another pickup
Fender Alder Strat w/ SD Invader, P90
Fender Blacktop Telecaster
Ovation Celebrity
Bolt BTH-100 w/ Marshall 1960A Lead
OCDP Avalon Series w/ Zildjian Custom A/K

I have a 3-way selector switch, and the guitar works in all 3 positions, so the neck works with the bridge. The EMG came with 2 pots- tone and volume. Each pickup has its own volume, but the both share the gain, which makes me worry that the neck is taking away gain that could be on the EMG.
that must be the case
if i were you i would just sell the EMG and get something like and X2N
its probably gonna cost quite a bit have that fixed, and its probably not worth it.
but, if you really want actives, you COULD just make the neck pickup active(you could put in a blackout, an EMG 60, and i hear the make jazz active pickups if you really want versatility)
Well, I really like the sound of the 81 (I tried out a 81/60 set on another guitar and was set on the 81), so I'd like to get the most out of my EMG since its barely a week old.

so then sell the seymour duncan and get some active pup in the neck(thats what i would do)
I looked on EMGs site and found this:

"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."

I want my EMG to sound like it should, so if one of the pickups is going to lose sound, I want it to be the passive one. So I'm guessing that I should use the low impedance pots?

What would the wiring diagram look like for that?
