Using the Behringer HA - 20R is easy. First, plug in your guitar to start playing. You can choose between the clean and overdrive channels according to your style. Use the 3 - band EQ to adjust the bass, middle, and treble to get your desired sound. For quiet practice, plug in your headphones. You can also connect external music players through the auxiliary input to jam along. When using the line out, connect it directly to a PA or recording interface.
Here are some things to note. Don't expose the amplifier to extreme temperatures or humidity. When moving it, handle it gently to avoid damage. To maintain it well, keep it clean by using a soft cloth to wipe it regularly. Also, make sure to turn it off when not in use to save power and extend its lifespan.
