Guitar Learning: First Shift

An attempt at phase shifts with ambient guitar loops

This short video is of two simple loopers that are ever so slightly out of sync. By the point at which the video begins, both of the loopers had accrued several layers of audio, all of it culled from an electric guitar. Some of the audio is shared between the two loopers, and some is unique to each separately. The starting point of each of the two loops is signaled when the given looper’s light briefly blinks. Shortly after the midpoint of this recording, the two loops can be seen to come into sync, and to then proceed to drift apart — to shift, to phase — again.

The looper used here is the original Ditto from TC Electronic (due to its popularity, several variations on the Ditto followed). I bought my first one used a few years ago, and have always enjoyed how simple yet effective its controls are. Despite having just one button and one knob, the Ditto comes with a manual that is nearly a dozen pages long, because different combinations of button clicks cause different processes. When I found another inexpensive secondhand Ditto, I picked it up just this afternoon with the express purpose of exploring asynchronous loops such as this one.
