Hi, I currently have an ec 1000t/ctm. I want to install Lace's drop and gain pickups which to my understanding are passive. Currently I'm running emg 81/85's which are active.

How would I be able to do this? Is it easy?

You just need to replace the pots and tone caps along with the pickups. Not a big deal.

The EMG preamp is housed with the pickup, so there's nothing to "gut out" there.
What pots comes with EMG pickups? Are they 250k or 500k? I'm switching out my EMG 81 for a Bill Lawrence L500XL.
