Built with seven footswitches, a 99 patch loop bank and a staggering 49 minutes of possible recording time, the Boss RC-50 Loop Station is one of the most expansive loopers available on the market. Capable of playing up to three stereo phrase effects at once during live performance and WAV-file supported with a USB port for even more playing options, the RC-50 is an excellent option for complex solo performance or keeping/playing loops in a math rock band.
