I haven’t started doing anything yet, but regarding the How, I got a rather good idea. From measurements, it was already clear that two additional Burns Tri-Sonic pickups would fit into the Mini May’s body. Here‘s a layout that should work quite nicely; the red lines are the additional routings that have to be done to the body. Still missing depth information, but otherwise complete.
Mounted on a picture of the body, it should look like that:
Without moving the bridge pickup (which wouldn’t be possible without ruining the finish, at least for me), it wont get much better. Should look quite good… how it sounds, I’ll see. Erm, hear.
