Digital processing gets cheaper and cheaper.
Guitarists love stompboxes.
The key advantages of digital stompboxes are their affordability, range of sounds, and ability to store programs. However, they are generally less intuitive to use than analog stompboxes, and because the knobs don't move as you change programs, you can rarely discern your current settings at a glance. Every one of the ingenious and ambitious devices covered here offers extraordinary bang for the buck. But in pursuit of competitive pricing, each makes its own compromises in sound, programmability, and hardware. They require four AA batteries that power the pedal for up to 15 hours.
