It would be quite wrong to say that a guitarist is just a musician. He is certainly the most important part of a band group, who sometimes be crazy and sometimes be normal according to the music he is playing. Do you think it is only the guitar that helps the guitarist in producing the rock? Of course not, because the professionals apply many inventive tricks by using some devices to produce something new. The maximum guitarists use pedals like the reverb pedal and delay pedal to produce new sounds. You can get a number of sound effects by using the delay pedal. However, first you need to learn some looping and modulation techniques to get the best out of delay or reverb pedal.
Start with the basic loop
Start with the simple exercise and that is the basic loop. Ring a chord that you can play comfortably and let it last till the four beats and then finish the loop. You will require a footswitch to hit the loop. So hit the footswitch and then play the chord, let it last for four beats and then hit the footswitch. Practice it and then listen how it sounds. It will be the first step towards becoming an expert.
Practice strumming with the delay pedal
Without using the delay pedal you cannot generate the best looper effects. The looper pedal offers enough controls to adjust the sound of delay and get interesting output in the mix. Start by hitting the footswitch and then strum the chords you want to play. Hit the footswitch again before at the end of the chord and then continue with the next chord. Timing of hitting footswitch is important in this exercise, so take care of that.
Creating a longer loop with a standard blue shuffle
Above mentioned two exercises will help you in gaining better control over the guitar and the timing of the loop. Now is the time to try something more musical and you can do that by trying a typical blues shuffle to produce longer loop. You can play a shuffle rhythm and then strum the chord with that shuffle. The groove decides where the loop will end; usually it ends with 4 bars in the loop. The delay pedal offers a longer loop timing to practice this exercise, so you can try it easily.
Experimenting like a professional by applying overdubbing
Those, who become expert in basic looping techniques, they can start experimenting with overdubbing. Do all the required set ups for loop and then hit the footswitch, strum the chords to play the loop. Thus, you can easily produce some appealing loops. Professionals always use overdubbing technique during the live concerts to create perfect loops for the track. Use of the delay pedal will make it a lot easier for you. The delay pedal allows you to last the loop for a long time. Normal delay pedals would offer a few selected functions, while latest pedals provide the guitarists with some more exciting features. So, invest in cutting-edge delay pedals, practice mentioned exercises and get what you want to produce.
