1. Locate the battery compartment cover on the rear of the amplifier.
2. Slide the cover open.
3. Connect a 9V alkaline battery to the battery clip, ensuring correct polarity (+ to + and - to -).
4. Place the battery inside the compartment and close the cover securely.

Connecting Your Guitar

Insert a standard 1/4-inch instrument cable from your guitar into the INPUT jack on the front panel of the amplifier.

Headphone Use

For silent practice, connect a 1/4-inch stereo headphone jack into the PHONES output located on the rear panel. This will mute the internal speaker.

External Power Supply (Optional)

The amplifier can also be powered by an optional 9V DC, center-negative power adapter (not included). Connect the adapter to the DC IN jack on the rear panel. Using an external power supply will bypass the internal battery.

Using the Tilt-Back Kickstand

The EVH 5150III Micro Stack features a built-in kickstand to angle the amplifier upwards for better sound projection during practice.

To engage the kickstand, simply pull it out from the rear bottom of the amplifier until it locks into position. To retract, push it back into its housing.

Operation

1. Ensure your guitar is connected and the battery is installed or an external power supply is connected.
2. Turn the VOLUME and GAIN knobs to their minimum settings.
3. Flip the POWER switch to the "ON" position.
4. Slowly increase the VOLUME to your desired listening level.
5. Adjust the GAIN knob to achieve the desired amount of overdrive or distortion.
6. Use the TONE knob to fine-tune the brightness of your sound.
7. When finished, turn the VOLUME and GAIN knobs down, then flip the POWER switch to "OFF".

Maintenance

Cleaning

Wipe the amplifier with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.

Battery Care

If the amplifier will not be used for an extended period, remove the 9V battery to prevent leakage and potential damage to the unit.

Storage

Store the amplifier in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

• No Power:
  • Check if the 9V battery is correctly installed and not depleted.
  • If using an external power supply, ensure it is the correct voltage (9V DC, center negative) and properly connected.
  • Verify the POWER switch is in the "ON" position.
• No Sound:
  • Ensure your guitar cable is securely connected to both the guitar and the amplifier's INPUT jack.
  • Check that the VOLUME knob is turned up.
  • If headphones are connected, disconnect them to enable the internal speaker.
  • Test with a different guitar cable or guitar to rule out external equipment issues.
• Distorted or Weak Sound:
  • Adjust the GAIN and VOLUME knobs. High GAIN settings will naturally produce distortion.
  • Replace the 9V battery if the sound is weak or distorted at lower GAIN settings, as this can indicate a low battery.
  • Ensure the guitar's volume knob is turned up.
