Do you need a more powerful looper? The BOSS RC-300 is the king of loopers. Record, playback, and control three separate stereo tracks, each with dedicated transport-control footswitches. Speaking of controls, the RC-300 boasts a master expression pedal, a 3-channel mixer, dedicated volume knobs for each channel, 16 onboard effects optimized for looping, and MIDI I/O. The BOSS RC-300 will record up to three hours of continuous music to the internal memory, and you can add effects as you do it. Save your loops externally via a handy USB port. You can also import and export WAV files. All the connectivity you could want is incorporated into the RC-300, there's even a phantom-powered XLR connection.
