BBDs—or analog shift registers, as they are properly called (or sometimes charge-coupled devices)—were first developed in 1969 as integrated-circuit (IC) chips containing a large number of storage cells (tiny capacitors, actually) and switching transistors.
In this manner, how do BBD chips work?
The “buckets” in a BBD come in the form of a series of capacitors inside the chip. Capacitors “carry” the signal much like the buckets carry the water. Because the capacitors are continuously filling and emptying, this slows down or “delays” the signal as it takes more time to pass through the BBD.
Furthermore, how do you make an analog delay?
Correspondingly, how do you use an analog delay pedal?
How does a PT2399 work?
In the PT2399, digitization is only used to delay the signal, nothing else ! The small DSP in the PT2399 stores only a sample of the sound in memory for a few milliseconds. Then it plays it back later without any sound processing added. Then, all the sound processing is done with 100% analog circuit.
How does an oil can delay work?
Oil-Can Delay
A motor drives a rubber belt to spin a flywheel fitted with a pickup inside the can. The oil stores signals electrostatically (rather than electromagnetically, as with a tape) and the pickup functions as the recording head, sloshing around in the oil to produce echo.
Is analog delay better than digital?
Analog delays can sound extremely musical and pleasing, and some guitarists don’t like their signal to be converted to digital if they can help it. But digital delays offer immense amounts of flexibility — including analog delay emulations, precise delay time control, preset memories, and other features.
Is tape delay analog?
Tape delays are 100% analog but most of the time you will see a difference between tape and analog when listing delays. Analog delays make use of capacitors to store and move an input signal along a line of capacitors.
What does analog delay sound like?
What is a bucket brigade used for?
A bucket brigade or human chain is a method for transporting items where items are passed from one (relatively stationary) person to the next. The method was important in firefighting before the advent of hand-pumped fire engines, whereby firefighters would pass buckets to each other to extinguish a blaze.
What is a tape delay?
Tape Delay simulates the sound of vintage tape echo machines. It can run at a free rate or can be synchronized with the project tempo. The effect is equipped with a highpass and lowpass filter in the feedback loop, making it easy to create authentic dub echo effects.
What is an analog delay?
Analog delays typically have a Bucket Brigade Device (BBD) chip that adds the delay effect. Analog delays will have a warmer tone, but will have less parameters for you to adjust. They won’t be able to go on forever, but they are great for those vintage tones and subtle delay effects.

When was bucket brigade delay invented?
Why is it called bucket brigade delay?
Bucket Brigade Devices are chips that contain lots of capacitors that delay audio signals. The name is derived from an old fire-mans technique where a line of people would pass buckets of water. They are used frequently in analogue delay pedals and stompboxes.
