The BOSS CH-1 Super Chorus Review

The BOSS CH-1 Super Chorus is a compact pedal for the electric guitar that creates a crystal clear top sound and a unique stereo effect; EQ adjusts the effect sound timbre.

Super chorus is characterized by high-frequency sounds and stereo effects, whose variations depend on the right and left speakers’ distance. Equalizer functions allow you to adjust the keys from a soft tone to a clearer one, ideal for a rhythm guitar. You can use this pedal with either a guitar or a bass guitar or even a keyboard.

The manufacturer claims that this pedal as a “classic chorus.” In my opinion, it is true. The sound is very predictable if I may say so. There’s a noticeable plus – the effect sounds good both in pure mode and in overload. There is no such clarity as competitors have, and the bypass performance isn’t perfect, but the sound is still delightful and stable.

Adjustments knobs:

  •  E.LEVEL (ratio of direct and processed signals),
  • EQ (tone control of the processed signal, however within minimal limits),
  • RATE (modulation of speed),
  • DEPTH (modulation of depth).

Sound: 9 points

Build Quality: 9 points. Everything is compact, functional, and reliable. The manufacturer gives a 5-years warranty.

Appearance/design: 8 points. The design is simple, doesn’t have any exquisite details, color is nice.

Features and functionality: 8 points.

The other thing that I like about this pedal, it can be used with both the battery and the power supply. However, the battery may not be long-lasting, as it’s digital, but still, it depends on the battery by itself.

The pedal has a stereo output. When using only one channel, the output will contain a mixed signal (processed and “dry” sounds), and when using both outputs, the processed and “dry” sounds will be separated channel-by-channel.

Standard adjustments: the volume of the mixing effect, a small equalization in the form of a boost or cutting off high frequencies, the speed and depth of the effect.

Value for money: 8 points. Reasonable price for a good result.

Some people may consider that the price is relatively high for such a pedal. But I think they are far from the truth. Of course, this is not a panacea, and this pedal doesn’t perform the best sound in history. But if you look at competitors and their prices, then everything becomes clear. It’s tough to find a better option and receive the same effect. Besides, it depends on personal preferences.

I especially like this effect performed by the Boss CH-1. You can easily tune up the very sound of Nirvana – Come As You Are. Of course, transparency is a bit missing, but it also depends on the guitar. I was totally satisfied with the result as I didn’t expect more on my Les Paul. Compared to the chorus in G-Major, the Boss pedal inferiors in depth. In Major, it can be adjusted so deeply that it will look like vibrato. In terms of speed, we have the same situation. But in general, both the effects are great.

All things considered, I assume this effect unit will suit almost any pedalboard. Moreover, many artists who use it will agree with me (e.g. Zakk Wylde, Jeff Beck, Joe Satriani, Robert Smith, Paul Gilbert, and many others).
