Use a standard 1/4 inch instrument cable to connect your guitar to the Input jack on the front panel. Turn the Volume and Master controls to minimum before plugging in, then gradually increase.
Can I use headphones with this amplifier?
Yes, plug your headphones into the Headphone Output jack. This automatically mutes the internal speaker for silent practice.
How do I switch between clean and overdrive channels?
The HBAC-20 has two channels. Use the Channel Select switch to toggle between Clean and Overdrive. Adjust the Gain control for more distortion on the overdrive channel.
The amplifier has no sound. What should I check?
First, ensure the power cord is securely plugged in and the Power switch is on. Check your guitar cable and that the Volume and Master are turned up. If using headphones, try unplugging them. Also verify the Speaker connection inside.

No, the HBAC-20 does not have an external speaker output. It is designed for its built-in 8-inch speaker only.
What does the 'Aux In' jack do?
The Aux In allows you to connect an external audio source like a smartphone or MP3 player. Use a 3.5mm stereo cable. This lets you play along with backing tracks.
How do I clean the amplifier?
Disconnect the amp from power. Use a soft, dry cloth to wipe the cabinet and control panel. Do not use water or cleaning agents, as they can damage the electronics.
