Watch the wiring which should go from the pickup to the bridge holder, if you pull it out they are complete s**t to get back in. the only
pickups I have are expensive Gibson ones, try
here they sell them for less than €10. also if you are going to refret don't take the binding off! and loosen the truss rod. If you need to borrow and glues and the odd set of tools, or need help give me a shout
