Boss Micro-BR Details:

BR in Your Pocket or Guitar Case

The MICRO BR is so small you can put it in your pocket! It measures just 136.0 mm x 81.0 mm x 21.4 mm (5-3/8" x 3-3/16" x 7/8"). But even though it's tiny, the MICRO BR packs an entire studio's worth of features into its tiny case. There are a dozen buttons on its front panel, nine knobs, and even a built-in microphone for quick capture.

Four Tracks & More

At its core, the MICRO BR is a four-track studio with four simultaneous playback tracks and two simultaneous record/input tracks.However, there's more to this recorder than meets the eye. Each of the four main playback tracks also has eight companion V-Tracks (for a total of 32), so you can record take after take after take, then pick your best material for final mixdown.

Drum Machine & Effects Onboard

Given the MICRO BR's small size and low price, you might be surprised to find the next two features onboard: (1) Almost 300 drum patterns are included. Use them for play-along inspiration or even as song foundations. The rhythms don't consume any of the four playback tracks - they play back independently. (2) A quality multi-effects processor is onboard, including a time-stretch algorithm for changing the tempo of your audio tracks without changing pitch - a great tool for both audio editing and phrase training. The Time Stretch feature can also be used with MP3 data; the MICRO BR's Center Cancel feature can be applied to MP3 data as well.

MP3 Compatibility

The MICRO BR is capable of loading and playing MP3 files. Load up your favorite guitar hero song via USB, slow down the tempo with no pitch change, and learn all of your favorite licks. You can even use the MICRO BR as a standard MP3 player. All of your data is stored on convenient SD (Secure Digital) media found in common electronics shops. The included 128MB card, for example, can record approximately 65 minutes of audio when one mono track is selected.
