Watch the Digital Delay online guitar lesson by Jeff McErlain from Guitar Effects Survival Guide
In the late 70’s digital technology boomed and made its way into the guitar community. It first entered in the form as rack units which were expensive and relatively large. As costs came down and the technology shrank, digital delay pedals were introduced into the market by Boss in 1984 with the Boss DD-2. Since then as technology advanced, delay pedals now offer many features in a very small box such as tape echo, analog, reverse delay, modulated delay, and loopers. The main difference between analog and digital delays is delay time and note clarity. Digital delays can produce multi second delay times whereas the Deluxe Memory Man offered a delay time of 550ms. Digital delay units also introduced the tap tempo function which is extremely useful when using delay as a rhythmic tool. There are many excellent companies producing excellent delay units, certainly a ground breaker was the Line 6 DL4 which is still popular today. Although I love the sound of a true analog delay, the latest offerings from companies like TC Electronics and Strymon offer so many options and analog emulation options it makes it a tough sell to stick with analog delays.
