Some effects subtly color a sound, such as a reverb unit used on a low setting, while others transform it dramatically, such as a distortion pedal used with electric guitar, with the overdrive set to its maximum level. Musicians, audio engineers and record producers use effects units during live performances or in the studio, typically with electric guitar, electronic keyboard, electric piano or electric bass. While guitar effects are most frequently used with electric or electronic instruments, effects can also be used with acoustic instruments, drums and vocals. Rackmounted or audio console integrated reverb effects are commonly used with vocals in live sound and sound recording. Examples of common effects units include wah wah pedals, fuzzboxes and reverb units. Effects are built into amplifiers reverb and distortion are the most common in 2. DJs and record producers, a format which typically contains multiple effects stompboxes and rackmount units, or they are built into the instruments themselves, as in the case of the Hammond organ, which includes chorus and vibrato effects inside the instrument chassis. A stompbox or pedal is a small metal or plastic box placed on the floor in front of the musician and connected to the instrument and the instrument amplifier with patch cords. Pedals are usually the least expensive format. Typically, one or more on off foot operated switches control a device that provides only one or two effects, with many pedals having knobs for controlling the volume, tone and intensity of the effect.

Terminologyedit. A display of assorted BOSS effects pedals. An effects unit is also called an effect box, effects device, effects processor or simply effects. In audio engineer parlance, a signal without effects is dry and an effect processed signal is wet. The abbreviation FX or FX is sometimes used. A pedal style unit may be called a stomp box, stompbox, effects pedal or pedal. Road Map Europe Professional. A musician bringing many pedals to a live show or recording session often mounts the pedals on a guitar pedalboard, to reduce set up and tear down time and, for pedalboards with lids, protect the pedals during transportation. When a musician has multiple effects in a rack mountedroad case, this case may be called an effects rack or rig. When rackmounted effects are mounted in a roadcase, this also speeds up a musicians set up and tear down time, because all of the effects can be connected together inside the rack case and all of the units can be plugged into a powerbar. FormatseditEffects units are available in a variety of formats or form factors. Stompboxes are usually the smallest, least expensive, and most rugged effects units. Rackmount devices are generally more expensive and offer a wider range of functions. An effects unit can consist of analog or digitalcircuitry or a combination of the two. During a live performance, the effect is plugged into the electrical signal path of the instrument. In the studio, the instrument or other sound sources auxiliary output is patched into the effect. Form factors are part of a studio or musicians outboard gear.

Pedals are often rectangle shaped, but there are a range of other shapes e. Fuzz Face. Typical simple stompboxes have a single footswitch, one to three potentiometers pots or knobs for controlling the effect, and a single LED that indicates if the effect is on. A typical distortion or overdrive pedals three potentiometers, for example, control the level or intensity of the distortion effect, the tone of the effected signal and the volume level of the effected signal. Depending on the type of pedal, the potentiometers may control different parameters of the effect. For a chorus effect, for example, the knobs may control the depth and speed of the effect. Complex stompboxes may have multiple footswitches, many knobs, additional switches or buttons that are operated with the fingers, and an alphanumeric LED display that indicates the status of the effect with short acronyms e. DIST for distortion. Some pedals have two knobs stacked on top of each other, enabling the unit to provide two knobs per single knob space. An effects chain or signal chain is formed by connecting two or more stompboxes. Effect chains are typically created between the guitar and the amp or between the preamplifier preamp and the power amp. When a pedal is off or inactive, the electric audio signal coming into the pedal diverts onto a bypass, an unaltered dry signal that continues on to other effects down the chain. In this way, a musician can combine effects within a chain in a variety of ways without having to reconnect boxes during a performance. A controller or effects management system lets the musician create multiple effect chains, so they can select one or several chains by tapping a single switch. The switches are usually organized in a row or a simple grid. To preserve the clarity of the tone, it is most common to put compression, wah and overdrive pedals at the start of the chain modulation chorus, flanger, phase shifter in the middle and time based units delayecho, reverb at the end. When using many effects, unwanted noise and hum can be introduced into the sound. Some performers use a noise gate pedal at the end of a chain to reduce unwanted noise and hum introduced by overdrive units or vintage gear. Rackmountsedit. Rackmounted effects in road cases.
