Roland JAZZ CHORUS User Manual

Main Features
The JC-22 is a 30 W stereo-input/output guitar amp featuring a transparently clean tone that faithfully
expresses the true character of your guitar.
5 Its unique stereo-input design lets you connect a stereo eect unit to the front panel and enjoy a
stereo eect using just a single amp.
5 A beautifully dimensional space chorus eect is produced by spatial mixing (allowing the direct
sound and eect sound to mix in the air).
5 In addition to a 3-band tone-stack EQ, it also provides a bright switch, giving you a rich palette of
tone settings.
5 With two independent power amps and two custom-designed 6.5-inch speakers, the JC-22 delivers a
stereo eect.
5 The enclosure is designed for strength and durability, made of hardened berboard and equipped
with corner protectors.
5 If a separately sold footswitch is connected, you can turn chorus and reverb on/o with your foot.

Owner’s Manual
Dimensional space chorus
This uses two completely independent amps and speakers; one
amp and speaker output the direct sound that is sent from the
guitar, while the other amp and speaker output a sound that is
subtly pitch-modulated. These two sounds are mixed in the air,
creating a softly spacious three-dimensional eect that is warm,
deep, and natural-sounding.
