Electronic tremolo effects were available on many early guitar amplifiers. Fender labeled them Vibrato, adding to the confusion between the two terms. [4] Tremolo effects pedals are also widely used to achieve this effect. Most settings on a tremolo effects pedal include depth of the tremolo (sometimes called intensity) and speed of the tremolo.
The first self-standing electronic tremolo effects unit may have been produced by DeArmond, in which a motor shakes a canister containing a "hydro-fluid" (not mercury as some people assume), oscillating the canister containing an electrolytic fluid that sends the signal to ground. Earliest references to DeArmond's tremolo unit date to 1941. [2]
When an LFO modulates amplitude (volume), it creates tremolo. On most synthesizers and sound modules, LFOs feature several controllable parameters, which often include a variety of different waveforms, a rate control, routing options (as described above), a tempo sync feature, and an option to control how much the LFO will modulate the audio ...
Spectrogram illustrating the difference between tremolo and vibrato. The terms vibrato and tremolo are sometimes used interchangeably, although (in the classical world) they are properly defined as separate effects. Vibrato is defined as a periodic variation in the pitch (frequency) of a musical note that is perceived as one fundamental frequency.
Alternate picking is a guitar playing technique that employs alternating downward and upward strokes in a continuous fashion. If the technique is performed at high speed on a single string or course voicing the same note, it may be referred to as "tremolo picking" [1] or "double picking".
In electronic effects, a tremolo is produced by modulating an instrument's audio signal with a sub-audible carrier wave in such a way that generates amplitude variations in the sound wave. [92] [93] Tremolo effects are built-in effects in some vintage guitar amplifiers. The guitar intro in the Rolling Stones' "Gimme Shelter" features a tremolo ...
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.
It is usually best performed when using a locking tremolo (whammy bar) such as the Floyd Rose version so that rapid changes in string tension do not take the strings out of tune. This allows the guitarist to pick a note, and widely vary its tone, either by quickly pushing (or pulling) the bar as far as it goes either way or slowly moving the ...
