Sorry, don't get on here much these days, but I'll try to answer any questions.
I still have 4 Euro Deans, 3 with EMGs and various preamps, and one with a Fishman Fluence system installed. I have a second Fishman system to install into one of the other 3, just haven't figured out which one. The Fluence system is REALLY good, FYI.
Just reading quickly, it seems like @Digital Larry has a modded Dean. If the electronics are EMG, whether a preamp or tone knobs, I'd encourage you to try other brands. I love EMG pickups, but cannot get along with the other stuff. Their preamps really don't seem to do much in the way of tone shaping, at least compared to other preamps. I would 100% say that an Audere or Darkglass preamp will do so much more than anything EMG has made (in my experience). Or, swap everything for a Fishman system and thank me later. lol
