When your guitar or bass is connected to the headphone port and monitoring is turned on, you may experience unwanted feedback due to crosstalk. GarageBand includes crosstalk protection to help protect against feedback caused by crosstalk. Crosstalk protection is especially useful when using high gain settings on a guitar or bass amp, or when using an overdrive or boost stompbox together with a high-gain amp such as the Modern Stack. In such cases, feedback caused by crosstalk can result in sudden, unpleasantly high output levels.

Crosstalk protection can change the sound of the instrument while monitoring is on, but the sound returns to normal when monitoring is turned off or another track is selected. You can turn off crosstalk protection to hear how it changes the sound; however, it is recommended that you decrease the volume of your iPhone to a low level before doing so.

1. Close GarageBand.

2. Open the Settings app, choose GarageBand, then turn Crosstalk Protection on or off.
