Most guitarists are curious creatures. Eventually they want pry open their amplifiers and see exactly how they intensify and modify their guitar's signal. Some guitarists take it a step further and want to modify or fix their own amplifiers. A small, solid-state practice amplifier like the Peavy Rage 108 is an ideal place to start learning about amplifier design. First released in the late 1980s, the Peavey Rage 108 is a relatively straightforward amplifier that requires little more than patience, common tools and a bit of know-how to take apart.
Remove the speaker wires. Speakers on Peavey Rage 108 amplifiers come with spade-lug connectors, so you should be able to just pull them out of their sockets. Take note of which wire belongs in which socket.
Unscrew the four screws on the top corners of the amplifier that aren't attached to the corner joints. This will release the head unit.
Push the front of the head unit until it is released from the amp chassis. Keep one hand beneath the head unit in the back of the amplifier to prevent it from falling. You will now have access to all of the electronic components. Use a soldering iron to take apart any of these electrical pieces.
Unscrew the screws surrounding the speaker in the back cabinet of the amp. Pull the speaker through the opening in the back of the amp.
Remove the other screws on the amplifier shell if you want to take apart the empty cabinet. The handle is attached by two screws. Take apart the cabinet itself by unscrewing the screws holding the metal corner joints in place.
Store each of the screws and components in a safe place as you work on the Peavey Rage 108.
Never try to take apart a guitar amplifier while it is plugged in, or you risk an electric shock.
