The 'Tap Tempo' feature is available for both the Spark app and the Spark amp.
- As soon as you turn on your Spark amp, the “TAP” button will always be flashing, indicating the tempo that is read by delay and modulation effects.
- To modify it, simply tap on the “TAP” button a few times at the tempo you desire. You should see the blinking speed change to whatever speed you just tapped.
