Adding a delay effect to your guitar is cool – it provides a fuller sound and makes a simple guitar part sound complicated. Most guitarists have a pedal to achieve this effect, but all you really need is two other guitarists.
Rob Scallon had the crazy idea to have himself and two of his friends play the same song on guitar together, but the two of them play on a different note value after Rob to achieve this delay effect. It’s a difficult task playing a song at a different time than somebody else, so it’s not surprising to see MANY attempts.
It’s impressive and entertaining to watch the process, but you’ll realize buying an effect pedal instead is a lot easier.
