  • If your instrument is plugged into an amp, please place your mobile device near the amp.

• Check your instrument:
  • The Rocksmith Tuner app is compatible with acoustic guitars or amplified electric guitars and basses. Unamplified electric instruments do not produce enough sound to be heard properly by the Rocksmith Tuner app.
  • If you’re playing an electric instrument, please make sure it’s connected to an amplifier.
• Instrument volume
  • Make sure your instrument’s volume isn’t too quiet while playing Rocksmith+.
