Jun has a nice stash of wood planks somewhere. But some luthiers are more active in acquiring high-grade tonewood. One day, he'll concentrate on perfecting his crafting. But that's not going to happen anytime soon. Nasa repair work ang pera para sa kanya and doon siya tututok until he's no longer flooded with it.
I think he finds electronics work pretty boring. Dati, he had an assistant who did the wiring jobs (unless Mang Raul Quesada pays a visit, wherein suwerte yung mga may ari ng mga naaabutan niyang gitara). I don't want to say anything bad about the assistant since he passed away a while ago and was quite a nice guy, but I wouldn't be surprised if may mga sablay siya na hindi napuna ni Jun.
That's why it was a good thing I learned how to do my own wiring. At least I don't have to run to him every time my guitar doesn't sound right.
As far as coil tapping goes, sometimes, it just doesn't work as nicely as one would imagine. Some pickups simply sound better than others when tapped. Furthermore, I've always been peeved with how coil tapping is used as an all-encompassing term in the quest for getting single coil sounds from humbuckers. First of all, that will never happen. Second, there are three typical pickup wiring methods: coil tapping, coil splitting and series/parallel switching, each bringing their own flavor. I've done them all. Personally, I think coil tapping is the worst of the three.
