Boss CH-1 Effects Pedal : Review


Simple but efficient

The general impression is that it is particularly suitable to the acoustic guitar, but this is a personal opinion. Anyhow, an interesting product with a good quality/price ratio.


E. Level

It adjusts the mix between the pedal and the direct signal of the instrument, a guitar or a keyboard. Substantially, turning it clockwise, it increases the volume of the effect in the overall sound.


Obviously, the equalization. By turning clockwise this knob the CH-1 boosts treble, while counterclockwise it cuts them and produces a warmer chorus.


The chorus speed.


The depth of the modulation.

Stereo outputs

When it is in stereo configuration, it uses the output A for the effect and B for the direct signal.

Sound and General Opinion

Let's say immediately that the natural context of the CH-1 is the effects loop, the acoustic guitar and a clean sound. In this context it makes really a good job and produces a pleasant chorus, perfect for the arpeggio, perhaps with too many highs, but the equalization control is very effective and can be used to cut higher frequencies for a better result.
Certainly, it can be used with an electric guitar too, but always in an effects loop or it will not make a good job.

Effects (Pedals and Floorboards)

  • Distortion | Digitech

    It provides a switch for the 2 modes: Crunch ( Overdrive) and Saturated (High Gain). The SC-2 is perfect for the 80's Rock, like Guns N' Roses, Motley Crue and so on. The high-voltage circuit preserves the guitar tone.

  • Competition Chorus
  • Chorus | Fender
    Competition Chorus

    A remarkable quality/price ratio. A very simple pedal, but it features two outputs and turns out really versatile. Substantially, it is surprising and turns out suitable to clean sounds, above all, but not only.

  • ME-50
  • Floorboards | Boss

    The speaker emulator is absent. The Tone Modify function comes with some preprogrammed equalization settings, substantially, ready-to-use presets. The expression pedal is always a very useful thing.
