So started with some preparations.
1. Check whether the Tele neck pickup ring fits: That was a no. By 1mm the holes didn't line up, so couldn't drill new holes next to it. Of course, I would be able to fill and re-drill... But more importantly, I didn't like the way it looked, see picture.
I am now considering a 3-ply white or off white pickguard, see picture.
2. Installed connectors: Initially it was my idea to be able to switch pickups quickly on this guitar and so I had bought these connectors (see picture). In the meantime, I have come back from this idea but still wanted to see whether it worked. It does!!
En suivre, To be continued!
