1. This video tutorial in Music & Instruments category will show you how to replace or install a new pickup in a Telecaster guitar. First you need to remove the strings so that you can take the bridge plate off. Pull the strings out from the back of the guitar. Take a calipers and measure the distance from the back plate to the front of the bridge and note down the readings. Then remove the four screws from the bridge plate and unscrew the telecaster panel. The pick up wire is connected between the bridge late and the telecaster panel. Remove the pick up from both ends and replace it with a new one and then screw back everything and you are done!
