Another one of the most common guitar effects would be the delay
. It is one of the most favorite guitar effects used by guitar players. It would also be often combined with an overdrive distortion or other guitar effects to achieve maximum results.
As the name implies, the delay would allow the sound to be played back at after a specific period of time. It can be played back several times or just one time into the recording.
Guitar players would use this effect to create some textures that over densely overlaid. The notes and the rhythms would then become complementary to the music. Some vocalists use a delay. It can also be used with other instruments to add some density or an ethereal quality into your playing. Delays that take about 10 seconds are used to create loops of an entire musical phrase.
The delay, as mentioned earlier, is one of the most used gadgets by guitar players. It has been used since the 70s and 80s and is still widely used today. However, the first digital delay that came with a pedal was the Boss DD-2. This was released in 1984. Some delay units are now rack mounted and are capable of incorporating other digital effects that are more sophisticated than pure delay like reverb and some audio time-scale pitch modification sound effects.
The more familiar digital delay systems normally function by sampling the input signal with a converter that would then turn the sound from analog to digital. The signal is then passed through a series of signal processors that then records it into a storage buffer. The play back is dependent on the parameters that you would set on the gadget. The wet or delayed output may also be incorporated with a raw and unmodified dry signal before or after it is sent to the digital-to-analog converter.
There are some digital delays that would offer other options. This includes controlling delayed signals time before playback. Commonly, delays would also allow the user to set the overall level of the processed signal versus the unmodified one to be modified and to be repeated. Some more sophisticated systems offer an audio filter even.
