The Essential Chorus Pedal

The BOSS CH-1 Super Chorus pedal 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 — there are 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 and a depth control, for a rich and tweakable 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 live 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 Yngie 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.

Super 90s vibes

I have a mxr black label chorus on a bigger board that sounds pretty much like a boss ce5 and wanted another chorus for my small nano ➕ board. Great sounding chorus pedal takes me back to the 80s and especially the 90s grunge Era, and its a boss so it will outlive me, built like a tank!

Boss Super Chorus Pedal

I bought this pedal to use on smaller gigs where I can run in directly through the PA without having to lug my Princeton Chorus amp around. It sounds great!

EXACTLY what I was looking for in a Chorus Pedal - Sweetwater ROCKS !!!

I have to give it the service team at Sweetwater ! As many know, their Customer Service and Sales Team is THE BEST! Has a Chorus Pedal I bought from them on site back in December. Messed with it a bit, but long story short.....checked into returning it, hoping for "maybe" some kind of trade in value. Well, between Sales Engineers Bevin Hall & Matthew Sturm, I received a FULL REFUND (less shipping) for a pedal I purchased 6 months ago !!!

After some discussion, Matthew suggested the BOSS CH-1 Super Chorus to compliment the genres I play (70s & 80s Classic Rock and Metal). I went ahead an ordered it at that moment. (I'd rather wait for refund than a pedal, right ?!) It arrived 2 days later in Toledo, Ohio from Ft. Wayne....AND....the returned pedal got back to them and my refund hit my bank account that same day.....PERFECT!!!!

After re-routing my board and cleaning up all the cables and power cords....VIOLA....smooth, shimmery Chorus thru my Rig! It adds a little something to the "Cleans" and even adds some extra tone to the HI-GAIN channel of my Marshall DSL 20watt Amp !

Thank you again to Sweetwater and the AWESOME PEOPLE that work there and TRULY CARE about their customers. As I've said in other reviews...I would drive the 1-1/2 hours from Toledo, Ohio to Ft. Wayne to buy a pack of Guitar Picks if I had to before I ever step foot in a "Big-Box" Guitar Store again!!

I have bought quite a few products lately from Sweetwater and all the AWESOME SERVICE and advice came from my main man Matt South! I am totally stoked and would not change a thing! Ibanez Genesis RG550 with Dimarzio UtoPia pickups, Mackie Pro FX12, 2 QSC12 Powered Speaks, Boss RC3 Looper, Beat Buddy, Boss Super Chorus, Boss Compressor, and SO MUCH more!
Thank you Matt and MERRY CHRISTMAS BRO!

quality classic chorus

Just what it says on the label, a good classic chorus sound. In the grand scheme of things, it's not the absolute thickest, vibrato-like chorus out there, so maybe check out the CE-5 if that's what you're looking for. If you want subtle to medium (or so) chorus that adds a pleasing, musical effect, then this is the way to go.

Not just for guitar! Every keyboard player should have a few pedals. This is one of my favorites and also check out the Moog pedals.
