Ross’s Classic Chorus Returns with Vibrant Pitch-shifting Vibrato
Lush, watery, and sporting an all-analog bucket brigade design, the Ross Chorus pedal marks the revival of a chorus classic. Devotees of the old-school Ross Chorus will be thrilled to hear that this JHS-built pedal perfectly captures the original model’s circuit in full vintage-accurate detail. From a super-subtle sway to choppy modulation, the Ross Chorus’s standard mode will cover all your analog chorus needs. Moreover, the Ross Chorus also includes an all-new alternate voice, accessed by the click of the side switch: Pitch vibrato mode. As the name implies, this setting unlocks a plethora of wavy and seasick analog vibrato tones to explore. It’s all topped off with a faithful replica of Ross’s iconic slanted top and recessed knob enclosure. Whether you’re a fan of the Ross Chorus’s initial incarnation or vintage-accurate analog bucket brigade tone, the Ross Chorus’s one-two punch of compelling chorus and vibrant vibrato makes it a truly must-have modulation pedal!

Switch between classic chorus and pitch vibrato
While the original Ross Chorus offered two knobs and a single mode, this JHS-built reimagining includes two different voices to choose from.
- Classic chorus: Although the original Ross Chorus’s design is very much in line with another classic blue-boxed chorus, scores of guitarists have long championed its dazzling depth and rich, full response. Whether you’re after shimmering ’80s-style cleans (especially when paired with a Ross Compressor!) or looking to add a bit of movement and texture to your dirty tones, Sweetwater guitarists find that the Ross Chorus delivers in spades.
- Pitch vibrato: From a design perspective, chorus and pitch vibrato are very similar — so why not combine them into a single pedal? Flipping the Ross Chorus side switch rewards you with a thoroughly vintage-style vibrato warble that takes you from a slight pitch-shifting pulse on subtler settings to an all-out seasick warble.


Myriad modern enhancements
From their iconic slanted enclosures to their recessed control knobs, JHS’s line of Ross pedals spares no expense when it comes to vintage authenticity. Of course, this comes as no surprise, considering Josh Scott’s status as one of the world’s foremost guitar pedal historians. That being said, the original Ross designs have pushed well into retirement age at this point, so JHS saw fit to make a few modern functionality upgrades to pair with the line’s thoroughly vintage-accurate tone. Each pedal now sports a soft-touch bypass and a drastically lowered noise floor for a much cleaner operation overall. Additionally, each and every pedal in the Ross lineup comes equipped with an alternate JHS-style voice, accessed by the click of their side-mounted switches.
Josh Scott’s Ross renaissance
The story of Ross pedals begins in the early 1960s with the birth of Kustom Amplification, Charles A. “Bud” Ross’s solid-state line of distinctive tuck-and-roll amplifiers. These amps would make waves in the hands of Creedence Clearwater Revival, Johnny Cash, and the Jackson 5. By the time the mid-1970s rolled around, the ever-restless Bud experimented with the still-growing market of guitar effects pedals. He ultimately chose Ross as the moniker for his series of stompboxes. While the pedals were by all accounts top-notch, Bud eventually sold the company and exited the music business for good. By the ’90s, Ross was all but a footnote in pedal history.
Thereafter, Ross pedals were relegated to cult-classic status — until 6-string virtuoso Trey Anastasio of Phish achieved his idiosyncratic sound courtesy of an old gray-boxed Ross Compressor. Since then, the demand for vintage-style Ross pedals skyrocketed, with precious little supply. Luckily for guitarists everywhere, JHS’s Josh Scott has teamed with Bud’s grandson, Cameron Ross, culminating in a complete relaunch of the Ross lineup! Each pedal is manufactured in JHS’s Kansas City, Missouri–based facility to the same exacting standards as the company’s own products, and to the same sonic specs that defined Ross pedals in their heyday. After decades of non-production and exceedingly rare reissues, Ross pedals couldn’t be in better hands.
