Go to Sim Lim tower. Don't go all out to get the cheapest multimeter u can find. Sanwa makes a reliable multimeter. Try getting one which can measure capacitance as well.
Ah, i don't think i'll be needing one after all. The past 2 days worth of research and study paid off, managed to get the pickups in, and functioning well too hehe Slowly, but surely getting better at this
