Thoughts on the EMG 85 after a few days...really unique frequency response and dynamics, and not sure how much of that is EQ vs compression.
The frequency response of the pickup is different than a passive, definitely not as big of a push in the upper midrange resonant frequency, but also seems like there may not be as much push in the low end either. This makes it feel a lot tighter and in some ways less forgiving. Think of the difference of running through an EQ pedal into an amp to change the gain and dynamic response. I wonder if that's why a lot of active pickup metal guys run through a boost pedal with the gain down and the tone turned up?
Frequency wise it seems a lot flatter. Because the passive sounds like it's pushed in the highs and lows, the active sounds like it's got a broad midrange push instead. But there's more extension in the very high end. This is probably why some people find them to be "hi-fi" sounding. Either way, I find I have to increase the gain and treble/presence.
It's very sensitive to height adjustments. Moving the high string side up or down by a turn really changes the response. I'm running them a bit higher than passive pickups right now. They don't seem to sound as good down lower.
Back to dynamics, like the EMG T set I can't tell if they are more or less compressed than passives. It doesn't clean up quite as well as a passive but also doesn't clean up the same way. The attack is very different, it seems faster and harder, and I think that's the big "tell" sonically between EMG and passives.
Still curious about a Luke set for my Ibanez AZ but going to think on it a minute.
