Ok, basically i have two basses and i want to switch the pickups. i've never done any bass modifcation besides chaning strings(yeehaw). i bought a soldering iron and don't even really know how to use it exactly. what's the best way to go about chaning to pickups? should i just pull the soldered connections off of the pickups? or should i pull them off the pots? also, any soldering tips/ advice on this matter would be greatly appreciated.
