Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.
A bucket brigade or bucket-brigade device (BBD) is a discrete-time analogue delay line, [1] developed in 1969 by F. Sangster and K. Teer of the Philips Research Labs in the Netherlands. It consists of a series of capacitance sections C 0 to C n. The stored analogue signal is moved along the line of capacitors, one step at each clock cycle.
The DL4 by Line 6, introduced in 1999, is a digital delay pedal. It is one of the first digital modeling effects units. [1] The DL4 features models of 16 vintage delay effects, including the Echoplex, Roland Corporation's Space Echo, and the Electro-Harmonix Deluxe Memory Man. [2] It is also used for looping. [3]
A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed ...
Echoplex EP-2. The Echoplex is a tape delay effects unit, first made in 1959.Designed by engineer Mike Battle, [1] the Echoplex set a standard for the effect in the 1960s; according to Michael Dregni, it is still regarded as "the standard by which everything else is measured."
The advantage to this system is that there are no potentiometers in the signal path to wear out and become "scratchy sounding" over time. Electro-optical circuitry is used throughout the classic Morley pedal line, which includes or has included volume pedals, delay pedals, chorus and phaser pedals, and many others.
Pedals are often rectangle-shaped, but there are a range of other shapes (e.g., the circular Fuzz Face). Typical simple stompboxes have a single footswitch, one to three potentiometers for controlling the effect, and a single LED that indicates if the effect is on. A typical distortion or overdrive pedal's three potentiometers, for example ...
The Phase 90 was the first pedal sold by MXR and helped launch the company in 1974. [1] The original model had a simple orange enclosure with a script style MXR logo. In 1977 MXR changed its logo to a block style. There was a transitional period in which some Phase 90s with script logos had box logo circuits, and vice versa.
