Introduction to performance types

I have been paying attention to audio effect recently, so I have reprinted several articles for learning.

 

Basically, the pedal with a single effect is better than the integrated effect, because most of the effect sound in the market is "false ", many of the combined effects emphasize that they have dozens or even hundreds of effects, in fact, the basic effects (Distortion, Time Modulation, Reverb, Pitch Shift, Wah, etc.) listed below are arranged before and after they are saved. If you are new to the effect generator, you may not even know the basic effect unless someone teaches you how to use it, let alone how to set a single effect, then arrange them! (Of course, DigiTech and ZOOM, which are non-effective, do not translate) The most important thing is that the effect of difference is too weak, if you really want to buy an effect generator that is economically acceptable, I suggest you buy an Rackmount Effect Generator (you can stack it on the shelf one by one, most of them are used in professional recording studios. Usually, the sound of the Rackmount effect generator with the foot pedal (midi controller) is not comparable to that of the traditional guitar effect generator. Lexicon, digiTech and Alesis are the authority of the Rackmount Effect Generator (not cheap ..) in addition, ZOOM and Peavy also have Rackmount efficient processors that are relatively inexpensive and sound-less. How to arrange the sequence of guitar effect .... (very important) Basically, there is no certain rule on the front and back arrangement of the effect device. Try it for every sample. As long as you like the sound of the effect, you should know the concept: different front and back la s will make different sounds! Sometimes you can adjust the front and back arrangement of two different effects and even make different sounds that are far different. Therefore, you can grasp the following sequence principle: guitar COMPRESSOR) -- WAH -- phich shifter -- DESTORTION -- DELAY -- equator -- speaker. After sorting out the order you want, you can tune the fine-tuning numbers of each effect one by one. "DELAY" can be replaced by PHASE, FLANGE, and CHROUS, you can also try to put all of them and change the front and back positions. The tone will be different! There is not a certain order in the front and back of the timer! Focus on what you like! Try different sorting order.

 

Distortion/Overdrive/Distortion
Principle: adding the noisy guitar signal to the Harmonics and expanding the Gain to make it distorted. As for Distortion, it sounds rough, overdrive sounds fine, just a little turbid (according to the famous Distortion/Overdrive effect: Ibanez's TubeScreamer: can make the speaker of the artificial synthesis circuit simulate a broken sound like a vacuum speaker, it's the Metal Zone of Stevie BOSS: Let's just look at the name. Needless to say, there seems to be no better Metal Zone on the market than the BOSS, and a dirty sound breaker! Ray Vaughan and Metallica's Kirk Hammett favorites!

 

Chrous/chorus
Principle: Use the Time Modulation principle to adjust the delay Time to 0.01-0.04 seconds, so that the guitar signal frequency (Pitch) is periodically changed, you can obtain soft, soft, and soft sounds like water. Most of the players usually buy Chorus after they have a sound breaker, because they basically use the sound breaker and Chours. For general rock songs, it is sufficient to cope with it, chorus is most often used with scattered electric guitar chords if you don't know what Chorus sounds like? Listen to Metalica's Eye Of The Beholder, which is played by Chorus and a prelude to Paradise City Of Guns N Roses.

 

Flange/Phase edge
Principle: Same as Chorus, the Time Modulation principle is used to adjust the delay Time to lower than 0.01 seconds, so that the guitar signal frequency (Pitch) by making periodic changes, you can get the sounds of "shoot" back and forth like a laser gun. The only difference between Flange and Phase is that Flange puts the signal processed by Time Modulation after a clean guitar signal, phase puts a delayed signal after Time Modulation processing before and after a clean guitar signal. The famous Phase effect is MXR Phase-90. If you want to create a guitar sound like Eddie Van Halen, MXR Phase-90 cannot be less. This is the secret weapon of Eddie Van Halen! As for Flange, the great Jimi Henderson Rix is very popular. According to a simple example, there is a song in the Chinese world called "the end of love ", listening to his guitar sound (like a Thundergun) is the effect of Flange.

 

Pitch Shifter/Transfer
There are basically two types of splitters. One is to input the guitar signal into the timer and output only one sound (the voice after the change ), the Chinese duck in the cartoon transmits the voice of a person to the streamer, and then increases the adjustment of the interpreter. The other is that after the guitar signal is input to this effect, there are two sound outputs (the original sound plus the changed sound). The second is usually used to strengthen the strength of the guitar (because of double sound ), or add a sound to the guitar. A good tuner can fine-tune the variation to 1/100 half tones (a scale has 12 half tones), while a poor tuner may be able to tune only one half tone, (generally, many of the integrated delimiters sold on the market claim to have the function of the trancoder, but you cannot adjust the degree of adjustment at all. You can only use the preset one.) In addition, A good interpreter can usually set the volume ratio of two output sounds to make multiple changes. We recommend that you use the "Harmonist" provided by BOSS, which is one of the most powerful pedal-type guitar splitters on the market.

Reverb/space Reverb Effect
If you stand in an empty room, the space you hear is Reverb. Common Reverb functions include Plate, Chamber, and Spring. Generally, guitar speakers usually have the Reverb function, if you adjust the Reverb to zero, you will feel the sound of your guitar is "dry ". Of course, a very good Reverb effect may be very expensive because it can make almost the same effect as shouting at an empty gymnasium, when recording a record, the song and guitar are often added with a little Reverb, which makes the song sound more powerful and more vigorous.

 

Wah/Wow
Principle: When the guitar player plays the piano, the doll pedal changes the degree of output tone Deformation Based on the force used by the foot to step up and down the pedal, that sounds like a baby crying. Jimi Henderson rix and Steve Vai often use doll pedals! If you cannot imagine the sound produced by the doll pedal in your mind, listen to the last piece of Solo Slash in Sweet Child O Mine. If you have a doll pedal, try adding a bit of broken sound or other effects in front of it, which may make a cool sound.

 

Tremolo/vibrato
Principle: The Doll pedal is made by changing the frequency (FM) of the guitar signal, while Tremolo is by changing the amplitude (AM) of the guitar signal) however, to achieve the effect, try to set the guitar sound button to rotate up and down in a regular manner, which is the result of Tremolo (volume change effect.

 

Acoustic Simulator/Wood guitar Simulation
As the name suggests, Acoustic Simulator can turn your violent electric guitar sound into a beautiful wooden guitar sound in an instant. Currently, there are BOSS "Acoustic Simulator" and ZOOM "504 Acoustic" on the market. The latter has 26 preset sounds for you to use or remember your own settings, four front-end amplifiers and loudspeakers can be added with four Reverb and Delay effects for on-site sound effects. They can simulate the sound of a wooden guitar, an electric guitar, a microphone, a wooden guitar, a nylon-string classical guitar, or even a 12-string wooden guitar, the most important thing is that his price is very cheap!

 

Compressor/volume Compressors
Principle: When the guitar volume reaches a certain level, Compressor compresses the volume of the guitar so that the volume does not increase too quickly. Like EQ, Compressor is also a good choice. In this case, we can only introduce basic principles and methods. If we want to explain Compressor thoroughly, it is not easy, compressor usually needs to set Threshold, Ratio, Attack, and Release time (compression start and end time ), knee (fast or slow compression mode), Key-in (plus compressed audio source conditions), and other compressors can be used to avoid excessive guitar volume (usually ratio can be set between and) knee can make the guitar sound smoother. Attack/Release time can determine the length of the guitar tail sound (1/4 to 1/2 seconds can be set). However, excessive use of the compression will cause the guitar to lose strength. It sounds muddy, even noise!

 

Noise Gate/Noise Eliminator
The principle is the same as that of the extender, except that Ratio is set to an infinitely large value. So when the guitar volume is lower than Threshold, Noise Gate begins to cut off all the sounds so that Noise can be controlled. In the recording studio, drums often use Noise Gate to cut unnecessary Noise.

 

Expander/extended
The principle is the same as that of the compressor. However, when the guitar volume is lower than Threshold (Threshold), the Expander starts to compress to control the noise.

Limiter/Limiter
The principle is the same as that of the compressor, except that the ratio setting is very high (for example,-1), so that the guitar volume will not increase after the Threshold is exceeded.

 

EQ/EQ
Principle: There are two types of EQ, one is the button type, you can choose the desired frequency range and the shape of EQ, the function is a little stronger, but more complex, it is usually used in professional recording studios. Another type of EQ is similar to the ordinary audio generator. There are many preset frequency ranges that can be adjusted to Gain (Gain), which is easy to operate. The EQ of the guitar pedal type is the second type. EQ basically does not change the guitar tone, but it can control the Gain of sound at various frequencies. EQ is like water, "When EQ is used, you can make the sound of the original guitar more distinctive (for example, you can enhance the high frequency of EQ to make the sound of the guitar more acute; you can also enhance the low frequency of EQ to make the guitar sound more powerful.) When your EQ is not used properly, you may make the guitar sound more difficult to hear than it was before EQ "! Therefore, if you do not know how to use EQ, or you do not know what kind of guitar sound you want, it is better not to add EQ.
