Connection Methods

There are several ways to connect your phone to a guitar amplifier, each with its own advantages and use cases. Let’s explore these connection methods in detail.

Using a Guitar Cable


  • Direct and straightforward connection.
  • Ideal for jamming or practicing with pre-recorded backing tracks.
  • Minimal latency.


  1. Connect one end of a standard 1/4-inch guitar cable to your guitar’s output jack.
  2. Connect the other end of the cable to the amplifier’s input jack.
  3. Ensure your phone is playing the desired audio source (e.g., a backing track app or music player).
  4. Place your phone near the amplifier’s speaker to pick up sound and provide a backing track for your playing.

Using an Auxiliary Input


  • Great for practice and jamming.
  • Provides more volume control and options for mixing your guitar and backing track.


  1. Locate the auxiliary input (AUX IN) on your guitar amplifier. It’s typically a 1/8-inch (3.5mm) stereo jack.
  2. Using a 1/8-inch stereo audio cable, connect one end to your phone’s headphone jack or audio output.
  3. Connect the other end of the cable to the amplifier’s auxiliary input.
  4. Adjust the volume levels on both your phone and the amplifier to achieve the desired mix of your guitar and the backing track.

Using Bluetooth or Wireless Connections


  • Wireless freedom and convenience.
  • Ideal for playing along with tracks without being tethered to your amplifier.
  • Great for performing and moving around on stage.


  1. Ensure your guitar amplifier has built-in Bluetooth functionality or an available Bluetooth adapter.
  2. On your phone, enable Bluetooth and search for available devices.
  3. Select your amplifier from the list of available Bluetooth devices.
  4. Once paired, play your desired audio source on your phone and adjust the volume and mix as needed on both the phone and the amplifier.

Using Guitar Amp Modeling Apps


  • Access to a wide range of amp models and effects.
  • Ideal for recording and sound experimentation.
  • Can replace the need for traditional amplifiers in certain scenarios.


  1. Download a guitar amp modeling app (e.g., AmpliTube, Bias FX, or Guitar Rig) from your device’s app store.
  2. Connect your phone to the amplifier using one of the previously mentioned methods (guitar cable, auxiliary input, or Bluetooth).
  3. Open the guitar amp modeling app and select your desired amp model, effects, and presets.
  4. Play your guitar through the app, and the sound will be processed and amplified by the amplifier.

Additional Considerations

Before you connect your phone to a guitar amplifier, there are some essential considerations and tips to keep in mind.

2.1 Cable Quality

  • Use high-quality cables to ensure a clean and reliable connection. Low-quality cables can lead to signal loss and interference.

2.2 Volume Levels

  • Start with the amplifier’s volume set low to prevent sudden, loud noises that could damage your equipment or hearing. Gradually increase the volume to your desired level.

2.3 Feedback and Noise

  • Be aware of potential feedback and noise issues, especially when using high gain or distortion settings. Position your phone and guitar away from the amplifier’s speaker to reduce interference.

2.4 Latency

  • When using digital amp modeling apps, there may be a slight delay (latency) between playing your guitar and hearing the processed sound through the amplifier. This latency can be minimized by adjusting the settings in the app and selecting a lower buffer size if available.

2.5 Power Supply

  • If your phone requires power while connected to the amplifier, ensure it’s adequately charged or use a power source to prevent battery drain.
