The legendary Jazz Chorus guitar amp series has been on the frontline of the music scene as a standard clean amp for more than 40 years. The Jazz Chorus has now gone beyond the framework of guitar amps and been launched as a rechargeable Bluetooth® audio speaker, the JC-01. In addition to the characteristic design and sound concept of the transparent stereo “JC Clean” that is common to the series, unconventionally high specs for Bluetooth speakers such as the three-band EQ are also inherited. The JC-01 of course comes with strong basic functions in a Bluetooth audio speaker, such as size-defying deep bass sound and a hands-free talk function. Enjoy listening to music with a genuine Jazz Chorus anytime and anywhere.



  • Listen to music anytime and anywhere with a Bluetooth connection and built-in rechargeable battery
  • Clear, high-definition sound field gives one the sensation of listening to JC series products
  • Unlike most Bluetooth speakers with a two-band EQ, the JC-01 offers outstanding tonal adjustability with a three-band EQ

  • Hands-free talking capability with built-in microphone
  • Audio In jack enables creative audio mixing with Bluetooth playback

Genuine Tiny Jazz Chorus Specialized for Audio Playback

The JC-01 is not named for the Jazz Chorus for no reason. Although it doesn’t have a guitar input, both the appearance and the philosophy of the world-standard guitar amp series are certainly inherited. Many artists have loved the reliability and durability of the JC series since its debut many years ago. The JC-01 Bluetooth Audio Speaker enjoys the same reliability and durability that have made the JC series of products a professional standard. Connect your audio player via Bluetoothand enjoy listening to music with the real JC anytime, anywhere.

What’s Jazz Chorus?

The JC Jazz Chorus is a series of guitar amps born in 1975. Since that time, its distinctive “JC Clean” tone and original “Dimensional Space Chorus” effect have been loved by many of music’s biggest names. These characteristics are achieved by a unique design, which is optimized for producing a clean sound.

The Jazz Chorus series has been able to maintain a standalone status in the music scene for decades. Even now, Roland’s Jazz Chorus Series is still evolving as a cutting edge product.

Commitment to Sound Quality as a Musical Instrument Manufacturer

The essence of the JC’s signature pure stereo sound is of course inherited as two two-inch speakers stuffed into the small body. The JC spirit embodies a high-definition and clear sound field, with a richness and transparency from mid to high range. A built-in passive radiator realizes powerful deep bass sound with this small size. Besides, the JC-01 has a three-band EQ, which is quite rare for this type of product. This allows you fine adjustment of the tone. Moreover, the JC-01 is replete with useful functions in various situations, such as an Audio In jack that enables mix playback with Bluetooth audio, and a hands-free function allowing you to talk on the phone even when your hands are otherwise occupied.
