Easy swap on a Squier P-Bass. The screws to attach the bridge to the body are smaller than stock. I reused the stock screws to install the bridge to the body. The saddles happened to be nearly identical to the stock bridge's but better finished. I was worried that the provided saddle length adjustment screws were too short on the E and A strings but they are ok. The bridge weighs more than the door hinge that is on stock Fenders but I don't think it makes a huge difference in sound or sustain. It looks better for sure. It has a good quality feel.If the bridge you are removing is set up ok, adjust the new bridge saddle length as close as possible before you install it. If the baseplate ok n the new bridge is thicker than on the old bridge, adjust the height of the saddles lower to compensate. A small Allen wrench is provided.
