The NUX CH-3 Chorus is a compact guitar effects pedal that offers a range of chorus effects with a true bypass design1. It is an analog pedal, and its delay circuit uses a low noise BBD (Bucket Brigade Device), which RockBoard's PedalPedia says provides a natural and clear sound1.
How it works
Chorus pedals thicken your tone by doubling the signal with a slightly delayed copy that drifts in and out of tune. In the CH-3, that delay is produced by a BBD chip, the analog component long used in chorus and delay designs. RockBoard's PedalPedia describes the result as a natural and clear sound1.
Power and switching
The pedal can be powered by a 9V battery or an AC adapter delivering 9V DC, center negative1. An LED indicator shows the status of the effect and the battery condition, so you can see when the chorus is engaged and when the battery is running down1.
The true bypass design, RockBoard's PedalPedia says, minimizes tone loss and gives you more control over your pedal1. With true bypass switching, the circuit is taken out of the signal path entirely when the effect is off.
Where it sits in NUX's chorus range
NUX makes several other chorus-capable pedals that approach the effect differently, including the DSP-based NUX Voodoo Vibe with Vibe and Chorus modes, the stereo NUX Mini SCF, the NUX Rivulet Chorus, the NUX Ukiyo-E Chorus and the multi-mode NUX MOD Core DELUXE.

Questions
Is the NUX CH-3 Chorus true bypass?
Yes. The CH-3 uses a true bypass design, which NUX says minimizes tone loss and gives you more control over your pedal. With true bypass switching, the pedal's circuit is removed from your signal chain entirely when the effect is off, so your guitar's signal passes through untouched until you engage the chorus.
Can the NUX CH-3 Chorus run on a 9V battery?
Yes. The pedal can be powered by a 9V battery or an AC adapter. If you use an adapter, it needs to deliver 9V DC with a center negative plug, the same standard used by most pedalboard power supplies. The LED indicator also shows the battery condition, so you can tell when the battery needs replacing.
Is the NUX CH-3 Chorus analog or digital?
The CH-3 is an analog pedal. Its delay circuit uses a low noise BBD, or Bucket Brigade Device, the same kind of chip used in classic analog chorus and delay designs. NUX says this gives the pedal a natural and clear sound.
What does the LED on the NUX CH-3 show?
The LED indicator does two jobs: it shows the status of the effect, so you can see at a glance whether the chorus is engaged, and it shows the battery condition, which is useful when you are running the pedal on battery power rather than an adapter.
