Using the Behringer HA-10G amplifier is easy. First, plug it into a power source using the EU plug. Connect your electric guitar to the input. You can choose between the clean and overdrive channels to get the sound you like. Use the 3 - band EQ to adjust the bass, middle, and treble for your perfect tone. If you want to practice quietly, plug your headphones into the headphone output. You can also connect an external device to the auxiliary input to play along with your favorite music.
When using it, make sure not to place it in a very hot or humid environment. Don't expose it to direct sunlight for a long time. Keep it away from liquids to avoid damage.
For maintenance, gently wipe the amplifier with a dry cloth regularly to keep it clean. If there's a lot of dust inside, it's best to have it serviced by a professional.
