On your Ditto Looper pedal, you’ll find the following.
Power Input
This is positioned to the right of the looper pedal just below the Audio Output. This is where you power your looper using something like the True Tone One Spot.
Audio Input
The Audio Input is positioned to the left of the pedal. This is where you connect your guitar.
Audio Output
The Audio Output is positioned to the right of the pedal. This is where you connect your amplifier.
Footswitch
The footswitch is operated by your foot. It’s the little clicker at the centre of the pedal.
Volume Control
This controls the overall playback volume of your loops.
USB Input
The USB input is used to connect the pedal to a computer for software updates. You’ll hardly ever need this.
