I just picked up a really nice boutique guitar that I would like to try some different pickups in (humbuckers), but the builder used braided pickup lead wire for all wires coming off the 3-way switch, and did not make the channel through the body wide enough for all of that, plus the braided wire of the two humbuckers, so needless to say, you can get NOTHING through the channel. I made the mistake of removing the bridge pickup (to try another one) and should have realized that I was going to be in trouble when I was trying to pull the bridge pickup lead wire back out of the body and I had to REALLY put some muscle behind it to yank it out. I ended up putting it back in (without trying anything new), but in order to do so, I had to insert a very small wire through, then solder the hot portion of the braided lead to that wire, and gingerly, yet forcefully, pull it back through...took me about half-an-hour. Needless to say, this has to change in order for me to try some other pickups. My question is this, can you guys recommend to me some narrower wire for such a task? By that, I mean, a particular gauge/brand I should procure for this project? Any links to the aforementioned wire would be welcomed as well. Thanks for your help!
