Hi Im reading up on how to change guitar PUs and it seems everything I've read suggest that when changing pickup one is better to unsolder from the pot and solder the new PU wire back onto the pot. Is there anything wrong with just hooking and soldering the shortned new PU wire to the already existing wire connected to the pot. This seems a lot easier to me....I have very little soldering expirence so maybe im overlooking somthing.....
