I ordered new pup's and got them yesterday along with new pots and switch. The place I ordered from assumed I have a standard strat with pickguard. My guitar actually has the wires in the back. Well they soldered everything as a kit thinking it is going into a pickguard so now some the the pup wires are too short for my guitar. Any harm in extending those wires? I think the smallest gauge I have may be some 20 or 22 gauge wire for car speakers. My plan is to loop each end and twist them together then solder and cover with shrink tubing. Or should I make them take the pup's back? They are Rio Grandes and it took a couple of weeks to get them. So if I send them back I am sure that I will have to wait another 2 - 3 weeks.
I got the Muy Macho set which is 2 Muy Grande's and the Stelly in the bridge. I cant wait to get them in there. I also went with Torres Engineerings BluesKaster setup. Hence it coming all soldered together already. I needed new pots and switch anyway so I figured why not try it out.
Chris is right - and a good twisted then soldered connection is as good as the wire itself! Also, using heat-shrink tube for insulation is better than electrical tape, which I find can unpeel into a sticky mess in future years.
