Yes there is. I don't think those old Roland systems would fit under a pickguard, plus there is that dreaded 21-pin connector that kinda needs to be on the side of the guitar. And since the whole brain of the guitar is probably on a PCB, it's impossible to do a different arrangement of the controls. And also, because of that, the guitar volume and 5 way were installed behind the bridge.
If you have an AS Jackson signature, you'll need to route, as the factory route is HSS.
I'm pretty sure they were Jackson pickups. I kinda assume those were in Dave's Burgundy/CAR Jackson too and that made him switch to Duncans later on.
The one problems if its Jackson pickups is that you can only buy them second hand from people who have removed them from Jackson Guitars. I could be completely wrong but that is how it is in Australia. With the routing it shouldn't be a problem that can't be solved in an hour or 2.
Unless you go for the early 00's specs. That version has a DiMarzio Super Distortion in bridge
Not going to argue with you, you seem to be the guru here on this topic
Yeah SD is also a ceramic high-output magnet, so there shouldn't be a lot of difference. Neck pickup was only ever used by Adrian on the beginning of Infinite Dreams so, there is not a lot of examples of that.
Thanks for the reply. Even though I've been playing guitar for 35 years, I'm still learning about these things
