The Boss RC-20XL is the mid-sized looper in Boss’s older RC-2x series, and the predecessor of the more recently released RC-30 Loop Station. In Boss’s older RC-2x series, the RC-20XL offered a wide range of features in a much smaller (and cheaper) package than the monster RC-50, but easier access to its features than the much smaller RC-2. The RC-20XL was actually an upgrade of the now obsolete RC-20, which only offered 5 minutes and 30 seconds of recording time, compared to the RC-20XL’s 16 minutes.Check Amazon Price
