Yeah, I'm a long time EMG guy too, but I'm planning on a full electronics + pickups swap in a newer guitar of mine and had considered putting in passives along with an EMG RPC pot, basically a pot that as you turn it up, boosts treble and cuts low end, like a built-in overdrive pedal EQ.
When dialed up to 10, the RPC's EQ curve looks like this, from the site:
Also, the RPC is an active component that buffers the signal from the pickups, so even if you use passive pickups, it will still convert that signal into the buffered, low impedance, extended crystaline highs thing that EMGs give you.
I'm going to put a recessed switch on the rear control plate that will allow me to bypass it or put it in the signal as the last thing in the chain. Best of all worlds! The guitar will be able to flip a switch and go fully passive if I want to use a fuzz pedal or just want to sound passive, and then when the switch is engaged, a fully active signal comes out of the guitar for when the situation calls for that as well. Kinda neat.
