The Boss BR-800 Digital Recorder is an audio studio you can take anywhere. The sleek design is made possible by touch-sensor switches and SD-card recording media. You can record up to 4 tracks simultaneously with 8 tracks of simultaneous playback plus an additional stereo track dedicated to the BR-800's built-in rhythm generator. The powerful onboard effects processor includes GT-10/10B effects, VE-20 vocal effects and harmonies, and COSM-based acoustic-guitar body modelling. An EZ Recording feature interactively guides you through the recording process, making the BR-800 a breeze to use, even for recording novices. A built-in stereo microphone makes instant "Song Sketch" recording possible. Fully portable and battery operated, the BR-800 lets you get ideas down wherever and whenever they come to you.
