Delays can be used for many purposes and they are arguably one of the most flexible effects available. By using short delays you can make a mono sound seem stereo, make a sound seem like it’s in a very large space or use it to add notes where the performer didn’t put them.

Adding notes to a performance is a very effective technique which some guitarists use to great effect with their pedal rigs. Some guitarists who use this effect well include The Edge (U2) and Nuno Bettencourt (Extreme), who by adding a single echo that is 3/16ths after the note was played can make it seem like they are playing more notes than they
actually are.

Listen to ‘Where The Streets Have No Name’ by U2 or ‘Flight of the Wounded Bumble Bee’ by Extreme to hear this effect in action.
