Get to know them!

The BOSS CH-1 Super Chorus pedal from Sweetwater offers up classic clean and shimmering chorus tones — it's arguably the best-selling chorus pedal on the planet and a stellar pick for any guitarist or keyboardist. The CH-1's four onboard controls let you take charge of your chorus sound with Effect Level, EQ, Rate, and Depth controls. Crank up the rate for a dizzying psychedelic twist or pull back the rate, turn up the depth, and use the BOSS CH-1 in stereo for a lush, wide wave.

Classic chorus tones, from clean and shimmering to lush and dizzying

No guitar or keyboard rig is complete without a high-quality chorus effect, and with the CH-1 Super Chorus, you'll be armed to dial in nearly every classic chorus sound. You can use the pedal's four controls — Effect Level, EQ, Rate, and Depth — to sculpt the feel and dimension of your sound until it's just right. The BOSS CH-1 can take you everywhere, from shimmering clean tones to lush ambiences to boat-rocking, dizzying swirls.

Two outputs for a rich stereo chorus sound

Take advantage of the BOSS CH-1 Super Chorus's two outputs for an incredible stereo chorus effect. It's a great way to give your guitar or keyboard motion, both onstage and in the studio.

BOSS guitar pedals: rugged, reliable, more than 10,000,000 sold

More than 10,000,000 BOSS guitar and bass effects pedals have been sold to players worldwide, including such top players as Yngwie Malmsteen, Dave Navarro, John Petrucci, Marty Friedman, Steve Vai, and Joe Satriani. You've also no doubt heard BOSS pedals recorded and onstage beneath the feet of bands of all genres, including Muse, the Killers, and Silversun Pickups. The reason for the success is clear: not only do BOSS effects pedals sound great, but they're also built like tanks and designed with serious use in mind. Each BOSS pedal is housed in a stomp-ready metal box and features a rubberized stomp area and base to help safeguard against slipping. So, whether you're a fresh-out-of-the-gate beginner, an axe-veteran designing your dream pedalboard, or anywhere in between, you can depend on BOSS's proven line of pedals to craft your tone.
