The JVC RV-NB1 Kaboom Series Boombox is a powerful CD/MP3 portable player with a funky feature -- a built-in guitar amp featuring twin super woofers for massive sound and rich, deep bass tones. This unit will play CDs, CD-R/RWs, and MP3, so you can access your favorite tunes from virtually anywhere in your music library. The RV-NB1 also plays all your old favorites on cassette and delivers clear AM/FM radio. The tuner stores 15 AM and 30 FM stations in its memory for quick tuning at the touch of a button.
