First is the standard or vintage floating system. This is also known as a Fender style trem although now just about every guitar maker uses them. This trem is fitted in the body through a hole cut out of the body which connects to a chamber on the back of the body. The trem is attached to the body with about 6 screws along the front edge and with 3 to 5 springs on the back of the body that hook to a claw anchored in the body. The springs provide tension to counter act the tension of the guitar strings. The trem bar can be pushed down into the body while playing to drop the pitch of the note being played.

There are basically 3 types of connectors used to connect speakers to amps. The first is ¼”, the same plug used for connecting input jacks to instruments. This plug works well for signal and low-wattage speaker applications, but was never designed to handle high wattage current (500 watts and up). The early alternative to this was to connect the bare speaker wire directly to binding posts on the amp. It made a good connection but took time and skill to connect properly. This evolved into what is now banana jacks.
