01Overview

Roland's JC-120 Jazz Chorus plugin models the two-channel, solid-state stereo amp that has been in production since 1975. Its main draw is a clean, transparent tone and the Dimensional Space Chorus that adds width and movement to whatever passes through it. Beyond guitar, producers use it on keyboards, drums and other sources. Extended parameters add mic type, mic position and room ambience controls, along with selectable stereo modes and tempo-synced chorus, which go beyond what the original hardware offered.

03In depth

Clean Solid-State Tone and Stereo Chorus

The plugin is built around the clean character of the original amp. Roland describes its solid-state stereo circuitry as central to the sound, with strong headroom that keeps the signal clean at high levels.

The built-in stereo chorus is the feature most users come for. It adds depth and spaciousness to chords, arpeggios and other material. Because the effect is tempo-synced in this version, chorus rate can lock to your session tempo for rhythmic movement.

Mic, Room and Stereo Controls for Production

Beyond the original hardware controls, the plugin lets you select the mic type, adjust mic position and dial in room ambience. These speaker simulation tools shape the tone after the amp stage, so you can tune the sound to fit a mix.

Two independent channels are modeled, so you can run separate clean and effected paths or blend two sources. Selectable stereo modes extend the spatial options for stereo processing inside your DAW.
