Tri Stereo Chorus

Two routes to the 80s stereo chorus in pedal form: the Boss DC-2 Dimension’s fixed-mode width against the Free the Tone Tri Avatar’s three-voice chorus.

Ghost Note Audio’s Swirls — tri-chorus, micropitch and compression in one pedal — as a whole 80s effects rack in a single box.

The other 80s stereo chorus: the Roland SDD-320 Dimension D rack, the Boss DC-2 that put it in a pedal, and the DC-2W reissue, side by side.

The Free the Tone Tri Avatar on its own — a three-voice stereo chorus, which is the tri-chorus idea in a box that fits on a pedalboard.

A tri-stereo chorus back in the rack and the single it produced — the sound doing the job it was built for rather than sitting in a demo.

The rack choruses put head to head — the closest thing to hearing the differences between them without owning them, and the reason the rack page keeps circling this sound.

Dan takes the tri-chorus apart — three modulated delay lines at offset rates, spread across the stereo field. The idea itself, separate from any one unit that does it.
