The ROSS Chorus is an analog chorus pedal and part of the ROSS ERA 6 series, a revival of the original ROSS circuits. Pedal of the Day describes it as "a respectful revival (not a remake) of the circuits that helped define modern effects," offering "a true analog bucket-brigade chorus" that "adds depth and warmth to any guitar setup"1.
Circuit and the ERA 6 revival
The ERA 6 series takes the original ROSS designs and rebuilds them with modern components. As Pedal of the Day put it, ROSS "took the soul and simplicity of the originals and rebuilt the technology for today's player: tighter tolerances, modern reliability and performance"1. The chorus itself is built around the classic V3207 chipset, the bucket-brigade chip associated with vintage analog modulation designs1.
The ROSS ERA 6 series is a revival of the original ROSS circuits, which the maker describes as "a respectful revival (not a remake) of the circuits that helped define modern effects"1. The idea, per Ross, was that "they took the soul and simplicity of the originals and rebuilt the technology for today's player: tighter tolerances, modern reliability and performance rebuilt from the originals"1. The ROSS Chorus in the series is built around the classic V3207 chipset1.
Controls and modes
The pedal keeps its control layout simple, in keeping with the originals:
| Control | What it does |
|---|---|
| Rate knob | Controls the speed of the LFO2 |
| Depth knob | Controls the depth of the modulation2 |
| Side-mounted button | Selects between Chorus and Vibrato modes2 |
Guitar World's reviewer Trevor Curwen noted the pedal is "sporting similar Rate and Depth knobs" to the Boss CE-2's arrangement3. The side-mounted mode button is what separates it from a straightforward chorus: in Vibrato mode it produces vintage-inspired vibrato tones, while Chorus mode covers the pedal's lush, shimmering textures12.
What reviewers said
Pedal of the Day's review of the ERA 6 version was strongly positive: "The ROSS Chorus is a standout among guitar pedals." The same review praised the analog design, saying "Its analog circuitry ensures smooth, organic sound that digital alternatives often struggle to replicate," and found "its intuitive controls make it easy to explore subtle movement or dive into rich, immersive modulation"1.
