Welcome to tremolo.com. A blog about the tremolo effect and it’s use.
Purpose of this site
The purpose of this site is to help you understand how tremolo works and how it can be used. The tremolo effect is one of the oldest guitar effects ever and has been used by many famous artists such as Jimi Hendrix, Pink Floyd, The Doors and more.
The tremolo effect is a modulation effect that varies the volume of a signal. The two most common forms of tremolo are amplitude modulation and frequency modulation. These two effects use different methods to produce the same effect, both involve varying the volume over time. This is commonly used in guitar effects and electronic music.
Frequency modulation varies the frequency of the sound to create an amplitude variation. This is a much more complicated way to produce this effect and not nearly as popular in use. Most tremolo effect pedals use amplitude modulation for the sound. Amplitude modulation is produced by varying the strength of any given part of an audio signal with a specific waveform pattern called LFO (low frequency oscillation). The LFO will be applied to the entire signal.
In simple terms, this is how it works:
An LFO, like a sine wave or square wave, will cycle at a certain speed (frequency) which is measured in Hertz (cycles per second). A typical rate for tremolo would be around 6-8Hz, but can go as high as 20Hz or as low as 0.5Hz depending on preference and application. In almost all cases the tremolo effect uses such low frequencies that you can’t actually hear them,
Tremolo is a vibration of the volume of a sound. Tremolo is created by varying the amplitude of a sound wave. The volume will be turned up and down quickly and evenly, creating a pulsating effect.
The tremolo effect may be used to create an artificial vibrato effect (pitch vibrates). This means that if you have an instrument that cannot produce vibrato, you could use a tremolo pedal to have your instrument produce this effect.
Tremolo is normally achieved in a signal by using an LFO (low frequency oscillator) or by some kind of signal pulsing device. The LFO would be routed to control some kind of gain device (amplifier, attenuator, voltage controlled amplifier), which then produces the variation in the signal.
Some early analog tremolos were produced with a rotating speaker system where two speakers are rotated in opposite directions to create an uneven speed rotation which creates the pulsating effect. Other early tremolos were produced with tubes that had bias voltage applied as well as current to alternate between full power and zero power on various parts of the tube’s structure.
Tremolo is a very unique effect. It’s one of the most common effects on many guitar amps and is also featured in many popular songs. The tremolo effect, unlike distortion or reverb, isn’t a desired effect while performing live. It was originally used to simulate volume swells or fade-ins and fade-outs. Tremolo is the simulation of amplitude modulation; it starts off loud then becomes soft, then loud again (or vice versa).
The simplest way to describe it, would be to say that it’s kind of like a fast, choppy volume knob. Think of turning the volume up and down very quickly and you have the basic idea behind the tremolo effect. In today’s world we can get this effect from pedals, rack units, and even guitar amplifiers (some come built-in with a tremolo circuit).
The original tremolo unit was actually invented by DeArmond in about 1960 and was called “The Trem-Trol” (later just “Trem-Trol”). This unit had two knobs. One controlled speed and the other controlled depth. It had two inputs but only one output because it didn’t use stereo; it
Experts say that tremolo is most effective when you have a clean sound. I have a Fender Vibrolux Reverb with a tremolo channel. This channel has a nice, clean sound and when you engage the tremolo pedal it gets even cleaner.
The first time I used the effect was in high school. I had a Fender Twin Reverb and loved the tremolo sound. It was very cool to play along with some Pink Floyd or The Cure and hear the sound change. That is what I love about music; it changes with time, place and emotion.
Tremolo is a musical term referring to a trembling effect. It is most commonly used with string and brass instruments to create either a tremolo or a wah-wah effect.
A tremolo effect produces changes in volume while a vibrato effect produces changes in pitch. Tremolo is created by rapid repetition of a single note, while vibrato is created by slow variation of the pitch of a single note.
Tremolo is a guitar effect that varies the volume of your sound. It is most commonly used in rock, blues and surf music. It has a smooth, gentle sound and can be used to create a pulsating sound.
Tremolo is often confused with vibrato also known as pitch-bending. Vibrato changes the pitch of your note, whereas tremolo changes the volume.
