I have a lovely 2012 SG 70s Tribute with mini humbuckers. So it has these pretty amazing 70s Tribute mini humbuckers set. Very warm, rounded, mellow. Really great. Yet..... I prefer the burstbucker Pro V in terms of bite and attack. Those have an alnico V magnet. The minis are more in line with the 57 classic set in terms of treble, and the 57s have alnico II magnets. So.... I would like to increase the treble response/bite by swapping the magnets to an alnico V. I dismantled the pick ups.... tried to desolder the covers from the plates..... And that's where it stayed. Got a 60w iron, I couldn't melt the solder blob!!! I got the wax potting flowing alright. I warmed the whole pick up, but it was absorbing too much heat too allow me to reflow the solder. Then I realised that if I actually managed to desolder it, I would get a pretty wax drippy mess of a pick up out, and getting it back in the wax messy cover would be a challenge too..... Any of you have done a magnet swap to a potted pick up? Any tips for actually melting the solder? How did the potting affect the procedure?
