• With a Liberator installed in place of a volume pot, changing pickups becomes fast, easy, and solder-free, but just as reliable. In fact, it's more reliable than a less-than-perfect solder joint. You simply insert the bare end of each pickup lead into one of Liberator's pickup connector stations and tighten the screw-clamp to lock it down. Turning the screw lifts up a carriage that locks the wire against a fixed pad, securing the connection in place. It's completely simple, and completely solid.
