The BOSS RC-10R is a looping pedal with rhythm parts on hand, and as such, is a boon for musicians who perform live in solo contexts, songwriters looking to explore rhythm parts in their music, and people who wish to practice against a beat rather than a metronome. The device is packed full of features that enable you to develop your music spontaneously, with moving rhythm parts that offer two song sections, intros and endings, and fills.
The user interface is streamlined and easy to understand. Tweak everything you need with onboard controls, and know what's happening at any one time thanks to easy-to-read visual indicators. Should you need it, expanded control is possible through external inputs, and you can control the unit over MIDI via 3.5mm jacks.
The unit offers both mono and stereo signal paths, so you can plug-in anything from a guitar to a keyboard. A large rhythm library is built into the device to handle most genres, and you can also import your own rhythms to personalize the device for your specific creations. An AC adapter is included to power the device.
