The BR-800's powerful onboard effects processor includes GT-10/10B effects, VE-20 vocal effects and harmonies, and COSM-based acoustic-guitar body modeling. EZ Recording feature interactively guides through the recording process. A stereo microphone is also built into the BR-800 for instant "Song Sketch" recording. No matter where you roam, you’ll never miss a moment of musical inspiration with the BR-800. Whether you’re creating intricate, multi-layered songs or point-and-capture field recordings, the BR-800 makes the recording process fast and easy. Beginners will love the new EZ Recording mode that interactively guides you through the recording process. Other helpful features include the convenient Retry function, which recues automatically to fix mistakes, and Song Sketch recording for instant, one-touch capture. There's also a built-in stereo condenser microphone plus a DR-880-quality rhythm generator for adding drum and percussion tracks to your songs. You can power the BR-800 from the included AC adaptor, or, for ultimate mobility, it can be powered from six AA batteries. Record anywhere! Stereo microphones are also built into the BR-800 for instant "Song Sketch" recordings - great for capturing song ideas (acoustic guitar and vocals, for example) from any location. Enhance your recordings with the powerful BOSS effects onboard the BR-800. Many of the effects are derived from BOSS's flagship processors, including vocal effects from the VE-20, COSM guitar/bass amps and effects from the GT-10 series, modeled acoustic-guitar body effects from the AP-1 preamp, which imparts pro-quality miked-up sound and rich body tone to line-recorded acoustic guitar. You'll be amazed at how much processing power is built into this little recorder, and how excellent the effects sound. The BR-800's USB compatibility enables a variety of functionality with computers. Connected to a PC, the BR-800 will function as a USB audio interface for recordings that utilize the internal effects. The BR-800 can also function as a control surface for DAW software.
