About the Liquier Analog Chorus

A chorus eect essentially copies the original signal, slightly alters the timing using delay,

and combines it with the original signal. By adjusting various parameters, a wide range

of eects may be produced. Just like a chorus of singers, the combination of multiple,
slightly diering sources creates blurriness of both pitch and rhythm that makes the

sound feel “wider” than the original. When used tastefully, chorus can add a very melodic

presence to a bass line. It provides a soft, ethereal sweeping eect that is useful for

thickening and for making a particular sound pop out of the mix. It can also be abused for

all kinds of great, specialized eects!

But here’s what makes the Ampeg Liquier Analog Chorus pedal unique:

• Instead of just a single delayed copy of the original signal, the Liquier makes two

copies... and one of those copies is a polarity-inverted mirror image.

• What happens next is that two separate triangle waves vibrate the pitch of the
copies. These waves are linked so that as one copy rises sharply in pitch, the other

wave falls at by the same amount. As the pitches criss-cross each other, some
high frequencies cancel each other out in a “comb-ltering” eect that rises.

• When the two copies are matched exactly in their pitch-shift, they briey disappear.
This is also known as “through-zero anging,” a rarity in true-analog eects pedals.

• All three signals (dry + delay + polarity-inverted mirror image) are blended
together via the Eect Level knob. The result is signal movement that swirls in a

3-dimensional manner.

Now go impress your friends with this new-found knowledge!
