I have a 7 string with EMGs and it sounds lifeless. Everything is compressed and flat. It has a 707/607 combo in it which I believe is the 81/60 but 7 string.
When I find the actives in my active Strat to be too compressed and lifeless, I use the volume knob on the guitar, often quite low. Running with a high master and low gain helps too. Some reverb can help, as well as using lighter gauge strings and picks.
I went to the Invader 7 which is funny I dont like the invader as a 6 string but i love it as a 7. Weird I know but the 7 string versions are close to their 6 string but not identical.
In my experience the emgs with 18v are pretty noisy. And yeah emgs are pretty compressed and midrangey. You might want to switch to passive to open up the tone and give you more picking control. Heck you could even give duncans new 7 string line up a go and tell everyone here what you think.
Noisy? Can't say I've ever noticed that. You may have had something else amiss in your wiring somewhere.
