Thomas Organ Cry Baby (1970) manufactured by JENWah-wah pedal (Dunlop Crybaby 535q) on electric guitar with distortion.
A wah-wah pedal, or simply wah pedal, is a type of effects pedal designed for electric guitar that alters the timbre of the input signal to create a distinctive sound, mimicking the human voice saying the onomatopoeic name "wah-wah". The pedal sweeps a band-pass filter up and down in frequency to create a spectral glide. The wah-wah effect originated in the 1920s, with trumpet or trombone players finding they could produce an expressive crying tone by moving a mute in, and out of the instrument's bell. This was later simulated with electronic circuitry for the electric guitar when the wah-wah pedal was invented. It is controlled by movement of the player's foot on a rocking pedal connected to a potentiometer. Wah-wah effects may be used without moving the treadle as a fixed filter to alter an instrument’s timbre (known as a “cocked-wah”[1]), or to create a "wacka-wacka" funk-styled rhythm for rhythm guitar playing.[2]

The first wah pedal was created by Bradley J. Plunkett at Warwick Electronics Inc./Thomas Organ Company in November 1966. This pedal is the original prototype made from a transistorized MRB (mid-range boost) potentiometerbread-boardedcircuit and the housing of a Vox Continental Organ volume pedal. The concept, however, was not new. Country guitar virtuoso Chet Atkins had used a similar, self-designed device on his late 1950s recordings of "Hot Toddy" and "Slinkey". Jazz guitarist Peter Van Wood had a modified Hammond organ expression pedal; he recorded in 1955 a version of George Gershwin's "Summertime" with a "crying" tone, and other recordings including humorous "novelty" effects. A DeArmond Tone and Volume pedal was used in the early 1960s by Big Jim Sullivan, notably in some Krew Cats instrumental tracks, and in Dave Berry's song "The Crying Game".
The creation of the modern wah pedal was an accident which stemmed from the redesign of the Vox Super Beatle guitar amplifier in 1966. Warwick Electronics Inc. also owned Thomas Organ Company and had earlier entered into an agreement with Jennings Musical Instruments (JMI) of England for Thomas to distribute the Vox name and products in the United States. In addition to distributing the British-made Vox amplifiers, the Thomas Organ Company also designed and manufactured much of the Vox equipment sold in the US. The more highly regarded British Vox amplifiers were designed by Dick Denney and made by JMI, the parent company of Vox. Warwick assigned Thomas Organ Company to create a new product line of solid state Vox amplifiers called Vox Amplifonic Orchestra, which included the Super Beatle amplifier, named to capitalize on the Vox brand name's popularity in association with the Beatles, who used the JMI English Vox amplifiers such as the famous Vox AC30. The US-made Vox product line development was headed by musician and bandleader Bill Page. While creating the Vox Amplifonic Orchestra, the Thomas Organ Company decided to create an American-made equivalent of the British Vox amplifier but with transistorized (solid state) circuits, rather than vacuum tubes, which would be less expensive to manufacture. During the re-design of the USA Vox amplifier, Stan Cuttler, head engineer of Thomas Organ Company, assigned Brad Plunkett, a junior electronics engineer, to replace the expensive Jennings 3-position mid-range boost (MRB) circuit switch with a transistorized solid state MRB circuit.
Plunkett had lifted and bread-boarded a transistorized tone-circuit from the Thomas Organ (an electric solid state transistorized organ) to duplicate the Jennings 3-position circuit. After adjusting and testing the amplifier with an electronic oscillator and oscilloscope, Plunkett connected the output to the speaker and tested the circuit audibly. At that point, several engineers and technical consultants, including Bill Page and Del Casher, noticed the sound effect caused by the circuit. Page insisted on testing this bread-boarded circuit while he played his saxophone through an amplifier. John Glennon, an assistant junior electronics engineer with the Thomas Organ Company, was summoned to bring a volume control pedal which was used in the Vox Continental Organ so that the transistorized MRB potentiometer bread-boarded circuit could be installed in the pedal's housing. After the installation, Page began playing his saxophone through the pedal and asked Joe Banaron, CEO of Warwick Electronics Inc./Thomas Organ Company, to listen to the effect. At this point, the first electric guitar was plugged into the prototype wah pedal by guitarist Del Casher who suggested to Joe Banaron that this was a guitar effects pedal rather than a wind instrument effects pedal. Banaron, being a fan of the big band style of music, was interested in marketing the wah pedal for wind instruments as suggested by Page rather than for the electric guitar as suggested by Casher. After a remark by Casher to Banaron regarding the Harmon mute style of trumpet playing in the famous recording of "Sugar Blues" from the 1930s, Banaron decided to market the wah-wah pedal using Clyde McCoy's name for endorsement.
After the invention of the wah pedal, the prototype was modified by Casher and Plunkett to better accommodate the harmonic qualities of the electric guitar. However, since Vox had no intention of marketing the wah pedal for electric guitar players, the prototype wah-wah pedal was given to Del Casher for performances at Vox press conferences and film scores for Universal Pictures. The un-modified version of the Vox wah pedal was released to the public in February 1967 with an image of Clyde McCoy on the bottom of the pedal.
Warwick Electronics Inc. assigned Lester L. Kushner, an engineer with the Thomas Organ Company, and Brad Plunkett to write and submit the documentation for the wah-wah pedal patent. The patent application was submitted on 24 February 1967, which included technical diagrams of the pedal being connected to a four-stringed "guitar" (as noted from the "Description of the Preferred Embodiment"). Warwick Electronics Inc. was granted U.S. patent 3,530,224 ("foot-controlled continuously variable preference circuit for musical instruments") on 22 September 1970.
Early versions of the Clyde McCoy featured an image of McCoy on the bottom panel, which soon gave way to only his signature. Thomas Organ then wanted the effect branded as their own for the American market, changing it to Cry Baby which was sold in parallel to the Italian Vox V846. Thomas Organ's failure to trademark the Cry Baby name soon led to the market being flooded with Cry Baby imitations from various parts of the world, including Italy, where all of the original Vox and Cry Babys were made.[4] JEN, who had been responsible for the manufacture of Thomas Organ and Vox wah pedals, also made rebranded pedals for companies such as Fender and Gretsch and under their own JEN brand. When Thomas Organ moved production completely to Sepulveda, California and Chicago, Illinois these Italian models continued to be made and are among the more collectible wah pedals today.
Some of the most famous electric guitarists of the day were keen to adopt the wah-wah pedal soon after its release. Among the first recordings featuring wah-wah pedal were "Tales of Brave Ulysses" by Cream with Eric Clapton on guitar and "Burning of the Midnight Lamp" by the Jimi Hendrix Experience,[5] both released in 1967. Hendrix also used wah wah on his famous song "Voodoo Child", in intro and in soloing. According to Del Casher, Hendrix learned about the pedal from Frank Zappa, another well-known early user.[6][7] Clapton, in particular, used the device on many of the Cream songs included on their second and third albums, Disraeli Gears (1967) and Wheels of Fire (1968) respectively. Clapton would subsequently employ it again on "Wah-Wah", from his good friend George Harrison's solo album All Things Must Pass, upon the dissolution of The Beatles in 1970.
In the late 1980s, the wah-wah pedal was revived in the British music industry by John Squire of The Stone Roses, who bought a wah-wah pedal to differentiate his sound from other contemporary acts of the time.[citation needed] Afterwards, the wah-wah pedal would also be used by bands such as the Happy Mondays and the Charlatans, and became one of the defining sounds of British guitar music in the late '80s and early '90s.[citation needed]

Uses
The main use of the wah-wah pedal is by rocking the pedal up and down. By doing this motion, the pedal reacts by sweeping through the peak response of a frequency filter up and down in frequency to create a spectral glide.
A different function of the pedal is to use it in a fixed position, which changes how an instrument sounds by selecting a certain frequency range. A guitarist using the wah in this way selects a position on the pedal and leaves the pedal there. Depending on the position of the pedal, this will boost or cut a specific frequency. This can be used for emphasizing the "sweet spot" in the tonal spectrum of a particular instrument. One electric guitar player to use the pedal in this way was Jimi Hendrix, who revolutionized its application by combining a Fender Stratocaster with stacked Marshall Amplifiers (in both static and modulated mode) for lead and rhythm guitar applications unheard of before then.
Another famous style of wah-wah playing is utilizing it for a percussive "wacka-wacka" effect during rhythm guitar parts. This is done by muting strings, holding down a chord and moving the pedal at the same time. This was first heard on the song "Little Miss Lover" (1967) on "Axis: Bold as Love," by the Jimi Hendrix Experience. The "wah-wah" and "wacka-wacka" effects are often associated with the bands on 1970s TV variety shows, like those of Sonny and Cher, Flip Wilson, or Donny and Marie Osmond; or with the soundtracks of pornographic films, the sound referenced in TV commercials for Axe body spray as "bow chicka wow wow."
Other instruments
Bass - A wah bass solo appears on "Mommy, What's a Funkadelic?", and all through "What Is Soul?" on Funkadelic's self-titled debut album (1970). Geezer Butler made extensive use of a wah pedal in the bass solo "Basically" on Black Sabbath's debut self-titled album (1970). Michael Henderson used a wah wah pedal on Miles Davis album On the Corner (1972).[16]Chris Squire of Yes used a wah-wah pedal on his solo piece "The Fish" on the album Fragile.
Trumpet - jazz/crossover records feature wind and brass instruments with the effect – Miles Davis's trumpet with a wah pedal was a well-known example.[17]
An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
Wah-wah is an imitative word for the sound of altering the resonance of musical notes to extend expressiveness, sounding much like a human voice saying the syllable wah. The wah-wah effect is a spectral glide, a "modification of the vowel quality of a tone".
Vox is a British musical equipment manufacturer founded in 1957 by Thomas Walter Jennings in Dartford, Kent, England. The company is most famous for making the Vox AC30 guitar amplifier, used by The Beatles, The Rolling Stones, The Kinks, The Yardbirds, Queen, Dire Straits, U2, and Radiohead; the Vox Continental electric organ, the Vox wah-wah pedal used by Jimi Hendrix, and a series of innovative electric guitars and bass guitars. Since 1992, Vox has been owned by the Japanese electronics firm Korg.
A guitar amplifier is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance.
Guitar Organ or GuitOrgan is a type of electric guitar with electronic organ components added, developed by Jennings Musical Industry as Vox Guitar Organ at latest in 1965. Similar instrument, GuitOrgan was developed by Murrell Electronics, circa 1967. On this type of instruments, each guitar fret is separated into six segments, creating independent contact switches for each string. The organ notes are keyed when a string touches a specific segment. An expression pedal is used to fade the organ sound in and out, while the guitar can be played at the same time.
Morley Pedals is the name of a guitar effects pedal company, famous for manufacturing wah-wah pedals and other treadle type effects for guitar. Morley pedals use electro-optical circuitry rather than a potentiometer to control the effect. The foot treadle controls a shutter inside the pedal that in turn controls the amount of light reaching a photoresistor. 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.
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards, and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone.
Electro-Harmonix is a New York City-based company that makes electronic audio processors and sells rebranded vacuum tubes. The company was founded by Mike Matthews in 1968. It is best known for a series of guitar effects pedals introduced in the 1970s and 1990s. EHX also made a line of guitars in the 1970s.
A vibrato unit is an electronic effects unit used to add vibrato to the sound of an electric instrument, most often an electric guitar. Vibrato units may be individual stomp boxes or built into multi-effects units, but are traditionally built into guitar amplifiers. Vibrato units are particularly used in surf music.
A fuzz-wah pedal is a stomp box containing both a fuzzbox and wah-wah pedal in series, allowing the user to distort ("wah") and use "fuzz" sounds as aesthetic effects on electric guitar or bass. They were developed to combine the sounds of psychedelic bands of the late 1960s–'70s.
The Dunlop Cry Baby is a popular wah-wah pedal, manufactured by Dunlop Manufacturing, Inc. The name Cry Baby was from the original pedal from which it was copied, the Thomas Organ/Vox Cry Baby wah-wah, first manufactured in 1966. Thomas Organ/Vox failed to register the name as a trademark, leaving it open for Dunlop. More recently, Dunlop manufactured the Vox pedals under licence, although this is no longer the case.
Clyde Lee McCoy, was an American jazz trumpeter whose popularity spanned seven decades. He is best remembered for his theme song, "Sugar Blues", written by Clarence Williams and Lucy Fletcher, and also as a co-founder of Down Beat magazine in 1935. The song hit in 1931 and 1935, in Columbia and Decca versions, and returned to Billboard magazine's Country (Hillbilly) chart in 1941. It was also played with vocals, by Bob Wills and his Texas Playboys, Fats Waller and Ella Fitzgerald.
The Fuzz Face is an effects pedal for electric guitar, used also by some electric bass players. It is designed to produce a distorted sound referred to as "fuzz", originally achieved through accident such as broken electrical components or damaged speakers.
Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone. Distortion is most commonly used with the electric guitar, but may also be used with other electric instruments such as electric bass, electric piano, synthesizer and Hammond organ. Guitarists playing electric blues originally obtained an overdriven sound by turning up their vacuum tube-powered guitar amplifiers to high volumes, which caused the signal to distort. While overdriven tube amps are still used to obtain overdrive, especially in genres like blues and rockabilly, a number of other ways to produce distortion have been developed since the 1960s, such as distortion effect pedals. The growling tone of a distorted electric guitar is a key part of many genres, including blues and many rock music genres, notably hard rock, punk rock, hardcore punk, acid rock, and heavy metal music, while the use of distorted bass has been essential in a genre of hip hop music and alternative hip hop known as "SoundCloud rap".
A combo organ, so-named and classified by popular culture due to its original intended use by small, touring jazz, pop and dance groups known as "combo bands", as well as some models having "Combo" as part of their brand or model names, is an electronic organ of the frequency divider type, generally produced between the early 1960s and the late 1970s. This type of organ predated, and contributed largely to, the development of modern synthesizers. The combo organ concept, at least in the context of mass-production, is thought to have arisen from popular demand, when smaller home organs were seen in music stores. Combo organs were probably originally developed in the United Kingdom, based on the Univox polyphonic version of the Clavioline, and some models included the inner-workings of Italian-made transistor accordions. They were the brainchild of necessity for portable organs of simple design, mainly for use in these small groups. Combo organs ended up having a major impact on the music scene of the mid- and late 1960s, particularly on rock and roll of that era.
The Mark is an electric guitar made by Vox. The instrument is also known as the Vox Teardrop, but this is not the official name. The Vox Mark came in three variations, a 6 string, a 9 string and a 12 string
Del Casher is an American guitarist and inventor. He invented the wah-wah pedal, the Ecco-Fonic, and the Fender Electronic Echo Chamber. He was the first to introduce the Roland Guitar Synthesizer for the Roland Corporation.
Keeley Electronics is an American manufacturer of effect units for electric guitars. The company, founded by Robert Keeley and operating from Oklahoma City, Oklahoma, started with the Keeley Compressor pedal along with modifications for effects by Boss and Ibanez.
Vintage musical equipment is older music gear, including instruments, amplifiers and speakers, sound recording equipment and effects pedals, sought after, maintained and used by record producers, audio engineers and musicians who are interested in historical music genres. While any piece of equipment of sufficient age can be considered vintage, in the 2010s the term is typically applied to instruments and gear from the 1970s and earlier. Guitars, amps, pedals, electric keyboards, sound recording equipment from the 1950s to 1970s are particularly sought. Musical equipment from the 1940s and prior eras is often expensive, and sought out mainly by museums or collectors.
A digital accordion is an electronic musical instrument that uses the control features of a traditional accordion to trigger a digital sound module that produces synthesized or digitally sampled accordion sounds or, in most instruments, a range of non-accordion sounds, such as orchestral instruments, pipe organ, piano, guitar, and so on. Digital accordions typically encode and transmit key presses and other input as Musical Instrument Digital Interface (MIDI) messages. Most digital accordions need to be plugged into a keyboard amplifier or PA system to hear their sounds.
