BOSS CH-1 Super Chorus
The Boss CH-1 is the standard for chorus among many guitar players. This simple yet effective pedal is a nice and cheap way to add a little bit of shimmer to your sound. Do not expect any breathtaking or multi dimensional effects. This is more of a simple, no frills stompbox.
External control: None
About as standard as it gets. There are no surprises or hidden features. The EQ knob might have a little less effect on the sound than one would expect.
There is not much beyond the standard chorus on this pedal. You can have more or less aggressive chorus, but overall, this pedal does the basics well.
Tonal Reproduction: 3/5
Although it might have a bit darker sound than one would expect, this pedal’s representation of your sound is on the good side of average.
Live application: 3/5
A standard for guitar players, this is a solid but not fantastic chorus pedal for a horn player.
