ToadWorks is a guitar effect brand owned by Ryan Dunn and Doug Harrison based in Spokane, Washington. ToadWorks is primarily known for manufacturing the Mr. Ed distortion pedal, the Barracuda flanger, and the Texas Flood overdrive.



ToadWorks was formed in 2001 in Mountain View, CA. During the first year of ToadWorks' existence, operations were located in Ryan Dunn's garage. By 2002 the company had moved to San Diego, where it continued to manufacture products. In 2003 the company was moved back up to San Francisco, where it occupied the top floor of the famous Hobart Building on Market St. In 2005, the company moved operations to Spokane, WA, where it continues to manufacture its increasingly diverse product line.

In January 2008, ToadWorks announced plans to release a flanger effect pedal called Barracuda. This new effect is intended to emulate the distinctive flanger effect heard on the Heart song of the same name. Using a custom-made flanger effect given to them by Howard Leese, ToadWorks initially attempted to reverse-engineer the circuit, but concluded the original circuit contained design elements that could not be duplicated using modern components, so a new circuit was designed. ToadWorks refers to this new circuit as the "Howard Leese Signature Model", although the true history regarding the effect from the actual recording is disputed. [1] A new release date for this product has been set for January 2009.

On April 13, 2013, ToadWorks USA released a press release announcing the re-branding of the product line to 'TEN Effects'.


The first product offered by ToadWorks was a distortion effect named Mr. Ed. The online community, specifically the Harmony Central effect forum, reacted with enthusiasm, describing the sound of the effect as being similar to the guitar tone on the first Van Halen record. Although the company denied any attempt to emulate the Van Halen sound, rumors persisted.

Wah-wah pedal effects unit that mimics the sound of "wah wah"

A wah-wah pedal is a type of electric guitar effects pedal that alters the tone and frequencies of the guitar signal to create a distinctive sound, mimicking the human voice saying the onomatopoeic name "wah-wah". The pedal sweeps the peak response of a frequency filter up and down in frequency to create the sound, a spectral glide, also known as "the wah effect". 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 are used when a guitarist is soloing, or creating a "wacka-wacka" funk-styled rhythm for rhythm guitar playing.

Scholz was an MIT-trained engineer who developed many of his skills working on audio-production equipment as a product design engineer at Polaroid in the early 1970s. A musician in his off-time, he developed a recording studio in the basement of the apartment building where he lived, utilizing many home-built devices. Recordings made in his home studio later became the debut album of the band Boston, while the Scholz's proceeds from the success of his band were used to found the company to further develop and sell market versions of his inventions. Many of the devices were marketed under the Rockman brand.

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.

A phaser is an electronic sound processor used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs of the waveform being affected is typically modulated so that they vary over time, creating a sweeping effect. For this purpose, phasers usually include a low-frequency oscillator.

Distortion (music) form of audio signal processing giving "fuzzy" sound

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 bass guitar, electric piano, 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".
