Audio-Looping Perfected

Shortly after its initial release, the original BOSS RC-505 was quickly lauded as one of the most intuitive and groundbreaking loop pedals created to date, finally offering DJ's, MC's, and club performers the chance and recording, overdubbing, and looping in real time, all controlled by hand.

The RC-505 MKII continues the legacy of this excellent loop station, and brings a whole host of new features to the table to surpass the original in every way.
