Have you ever wondered how to build a guitar amplifier? Building a guitar amplifier can save money and allow you to get just what you are looking for out of your amplifier. You do not need to have a large background in electronics either. Learning how to build a guitar amplifier can also lead to a rewarding side business.

To build a guitar amplifier you will need:

  • An old amplifier box.
  • Screwdriver
  • Wrenches
  • Pliers
  • Amp instruction guide. These can be found at most music stores.
  • Electrical wire
  • Clamps
  • Speaker
  • Pre-amp
  • Power amp
  • Knobs and switches
  1. Place and install the pre-amp. The pre-amp is the area of the guitar amplifier that you will find your knobs and switches. The bass and treble controls will be in the pre-amp area. The pre-amp is the area of the guitar amplifier that will be receiving any electronic signals coming from the guitar.
  2. Place and install the power amp. The power amp is going to be taking the electronic feeds from the pre-amp and sending them through the speakers. Your amp instruction guide will be able to walk you through each step of installing the power amp properly. It is vital that you pay close attention to the amp instructions during this stage of building your guitar amplifier. If you do not and rush through this step then you may have an amplifier with no sound.
  3. Install your speakers. This step is where you can be a little creative and customize the guitar amplifier to your liking. As the speakers get larger so does the sound that they put out. If you want your guitar amplifier to have a lot of sound then get the largest speakers possible for your guitar amplifier box.
  4. Perform a sound check. Now that all of your components are in place it's time to hook up your guitar and perform a sound check on your guitar amplifier. Play around with the bass and treble to ensure that they are working properly. Listen for any issues from your speakers. After you have checked everything you are ready to go.

Building your own guitar amplifier should only take a few hours. Companies like Crutchfield offer great free amplifier manuals that will make setting up individual components of your guitar amplifier easy. If you find that building your own guitar amplifier from scratch is a bit to daunting then you can also find great amplifier kits that will give you the same effect and knowledge as building your own will.
