There are two extremes when it comes to looper pedals. On one side, you have things like the Boss RC-300, which cram as much functionality in as possible with the aim of providing every feature you could possibly need in a single (often obnoxiously large) unit. On the other, you have pedals like the Ditto from TC Electronic, which scale things back to the key offering, in the name of reducing the footprint of the pedal (not to mention the price) while still providing the core functionality you’re looking for.
