Connect an electric guitar to use with GarageBand on Mac
You can connect an electric guitar or another electric instrument to your computer to play and record in an audio track, and use the included amps and pedals to shape your guitar sound. There are several ways to connect an electric instrument to your computer.
After you connect an electric guitar, you choose the input source for the track you want to record in, and optionally turn on monitoring. Monitoring lets you hear yourself play so that you can hear the part you want to record as well as the rest of the project.
The Monitoring button lights orange to indicate that monitoring is turned on.
To avoid unwanted feedback, you should usually turn off monitoring when you’re not playing or singing. Using headphones rather than speakers to listen to your projects can also help eliminate feedback.
