1 Select Guitar Amp
Create a new track in your GarageBand project and swipe through the sideways-scrolling instrument selector list until you see the Guitar Amp instrument. Tap to select it.
2 Set input level
Plug in your guitar and tap the Input button in the top-left corner. Drag the Input level slider left or right so that loud playing illuminates the meter’s yellow stage.
Tap the Monitor button in the Input Settings menu to turn monitoring on. This enables you to hear the guitar sound through the virtual amp as you play and record.
4 Tune up
Tap the tuning fork button to access the built-in tuner function. Play an open string and watch the display. When the note is in tune, its name will turn blue.
5 Choose guitar sound
Tap the name at the top of the screen and choose the preset you want to record with. You can also save presets you’ve edited by tapping the Save button.
6 Switch amps
You can adjust controls just as you would on a real amp. Touch and drag vertically to change settings, or swipe horizontally to switch to a different amp model.
