Main Features

The JC-40 is a 40W stereo-input/output guitar amp featuring a transparently clean tone that faithfully 

expresses the true character of your guitar.

 

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

Its unique stereo-input design lets you connect a stereo effect unit to the front panel and enjoy a 

stereo effect using just a single amp.

 

5

A beautifully dimensional space chorus effect and a unique vibrato are produced by spatial mixing 

(allowing the direct sound and effect sound to mix in the air).

 

5

With two independent power amps and two custom-designed 10-inch speakers, the JC-40 delivers a 

stereo effect and sound that won't get buried in the ensemble.

 

5

The enclosure is designed for strength and durability, made of hardened fiberboard and equipped 

with corner protectors.

 

5

If a separately sold footswitch is connected, you can turn chorus/vibrato, reverb, and distortion on/off 

with your foot.

JC-40

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 effect that is warm, 

deep, and natural-sounding.
