Some of the coolest looking effects out there come from the British company Rainger FX. Their latest, a sidechaining pedal, is more typically-shaped than their usual fare but still reflects their creative graphics and off-center sensibility.
Sidechaining is a popular effect in modern recording. It can be used subtly, as in sidechaining a rhythm guitar with the kick drum, so that each time the kick drum hits the guitar volume dips slightly, or more intensely in dance music, to make the signal completely disappear with each kick drum beat. The Rainger FX Deep Space Pulsar ducks your instrument’s volume in this manner, creating a choppy effect similar to a slicer like the Boss SL-20.
