JC-120 Jazz Chorus Sound Examples

The benchmark in solid-state sound.

The Roland JC-120 Jazz Chorus is a benchmark voice in the amplifier world, heard on countless hit tracks through the ’70s, ’80s, ’90s, and beyond. Its stereo solid-state circuitry is a big part of its uniqueness and contributes to its signature sound. Famous for its exceptional headroom, it stays clean even at high volumes. The design translates every detail of your playing dynamics with precision, providing a snappy, articulate response that’s also warm and inspiring.

Pedal platform.

With its exceptionally clean and transparent tone, the JC-120 is an ideal pedal platform for players who want their effects to shine through without unnecessary coloration. The JC-120 software offers the same pristine and punchy voice, allowing you to plug your pedalboard into your audio interface and capture solid tracks with your favorite external effects.

Lush stereo chorus.

The JC-120’s built-in Dimensional Space Chorus is a cornerstone of its iconic sound. This lush, immersive effect adds unparalleled depth and spaciousness to chords, arpeggios, and any other audio you run through it. The unique analog circuitry has been meticulously analyzed and recreated in the JC-120 software, ready to enhance your music with its unique, captivating character.

More than a guitar amp.

Because of its unique design and wide-spectrum sound, the JC-120 is a perennial favorite for producers—not only for guitars but other instruments as well. With multiple instances of the JC-120 in your DAW, you can add life and depth to electric pianos, plucked and lead synths, drums, and more.

Double the channels. Double the fun.

The JC-120 software replicates the two independent channels of the original amp and expands on their capabilities. Each channel delivers that stellar clean tone, giving you the flexibility to blend instruments, create separate signal paths for clean and effected sounds, or explore unique stereo-processing techniques within your DAW.

Modern features to define your sound.

The JC-120 software is filled with powerful features for modern production. Use the selectable stereo modes for spatial configurations that go beyond the original hardware’s capabilities. Sync the iconic chorus effect to your DAW’s tempo, ensuring perfect rhythmic integration with your tracks. And with the advanced speaker simulation, you can sculpt your tone with unprecedented realism. Select from a range of microphone types, fine-tune their placement, and dial in the perfect amount of room ambience to create a truly immersive sonic experience.
