"Bucket Brigade" Technology

The NU-X AD-3 is an analog delay with all the great characteristics of the sought after "Bucket Brigade" technology which produces a warm and successful delay.

With its 600 ms of maximum delay time and feedback that can be pushed into buildup, you can achieve a wide range of your favorite delay sounds.

"Bucket Brigade" refers to a technique that places several thousand capacitors on a chip and allows each capacitor to hold a very small amount of the audio signal (less than one millisecond). These buckets are placed in a line (brigade) so that the signal can be passed from one capacitor to the next.

An urchip regulates how fast the signalpassess throught the "brigade" and thus creates a delayed version of the original signal, which can be heard as an echo effect.

Since capacitors are not optimal for transmitting an audio signal, the sound will deteriorate, the longer the signal will flow through the chain of capacitors, which you will hear as a loss of tweeter and clarity.

This "error" is part of what makes "Bucket Brigade" pedals so popular among guitarists.

The "Bucket Brigade" technology gives NU-X AD-3 the pure analog delay effect with a heat that is not obtained from other digital delay pedals.
