Clean, Clear, and Classic Chorus
Some pedals come and go, but the Boss CH-1 Super Chorus has been on pedalboards since 1989 for a reason. It just sounds right. Whether you want a gentle shimmer behind clean arpeggios, a swooping wide stereo spread running into two amps, or a faster psychedelic swirl that turns a simple chord into something altogether more interesting — the CH-1 handles all of it without a lot of fuss.
This is Boss's classic analog chorus circuit, and it shows. The tone stays clear and defined even as the effect deepens, which matters a lot when you're playing with a band and don't want your guitar disappearing into a wash. It works equally well for guitarists and keyboard players, making it a genuinely versatile addition to any rig.
Four knobs. One footswitch. Two outputs. If you've been looking for a no-drama chorus pedal that delivers every time you stomp it, the CH-1 is a strong starting point — and for a lot of players, the ending point too.
Four Knobs, Full Control
The CH-1's control set is straightforward but surprisingly deep. The Effect Level knob blends how much chorus sits in your signal — from a barely-there thickness to a full, wet wash. Rate controls the speed of the modulation, and Depth determines how far the pitch wobbles, so a slow rate with high depth gives you that wide, rolling wave, while a faster rate and moderate depth lands squarely in classic 80s chorus territory.
The EQ knob is what separates the CH-1 from a lot of simpler chorus pedals. It lets you adjust the tonal character of the effect itself — brightening up a darker guitar or smoothing out the highs when the chorus gets intense. It's a small thing that makes a noticeable difference in how the pedal sits in a mix.
Stereo Outputs Open Up Your Options
The CH-1 has a single mono input and two 1/4" outputs — Output A and Output B — so you can run it in mono straight into your amp or spread the stereo effect across two amps for a genuinely wide, room-filling sound. When you're running stereo, the chorus effect pans variably between the left and right speakers, which adds a sense of space that a mono setup simply can't replicate.
Even if you're only using one output, the stereo circuitry behind the scenes is part of what gives the CH-1 its characteristic clarity and depth. It's a compact pedal that punches well above its footprint when you give it the right signal chain to work with.
Built the Way Boss Builds Things
The CH-1 runs on a 9V battery or the Boss PSA-series AC adaptor (sold separately). It uses Boss's buffered bypass, which helps maintain your signal integrity across a long cable run or a packed pedalboard — something worth considering if you've got a chain of true-bypass pedals that might be loading down your tone. The build quality is the same rugged die-cast chassis Boss has been using for decades. It's the kind of pedal you put on your board and stop worrying about.
Boss backs it with a five-year warranty, which says something about how they stand behind the product.
