8970 five-second length audio recordings of real electric guitar sounds
All notes of a standard tuning electric guitar processed through 12 different effects
EGFxSet contains recordings of all clean tones in a Stratocaster guitar, with augmentations by processing the audios through twelve electric guitar effects. Similar datasets apply effects using software, EGFxSet in contrast uses real guitar effects hardware, making it relevant to develop MIR tools with applications on real music. Annotations include all guitar and effect parameters controlled during our dataset recording. EGFxSet contains 8970 unique, annotated guitar tones, and is published with full open-access rights.
All possible notes of an standard tuning electric guitar were recorded using the instrument
input of an Audient iD14 audio interface. Using the interface output, the recordings of each sound
effect were processed for recording
using the line input of the same interface. Both, the previously recorded clean guitar sounds
and
the processed recordings were normalized.
All the sounds of the dataset were annotated by a professional guitarist. Each file’s annotations
are:
Existing datasets use software emulations of analog gear to apply effects on clean
guitar recordings, and few include effect parameter annotations. As a result, there is a need for
datasets featuring
recordings of clean electric guitar tones, augmented using real effects hardware, and
including annotations of effects and guitar settings.

All 138 possibles notes with each of the 5 pickups of an American Fender Stratocaster plucked by a 2.0 mm thick pick
Carefull annotations of each note, string and fret position, and the effect parameters applied
Analog gear effects with and without digital components 12 popular effects are divided into four categories: Gain, Modulation, Delay, and Reverb 3 different effects per category
TubeScreamerMini: A compact version of the iconic TS-808 Saturation effect from Ibanez. The pedal used was made in Japan in 2019. BD-2: A widely used overdrive pedal from Boss Company. The version used is a 2018 model made in Taiwan and has the same schematic as their first Blues Driver pedal released in 1995. RAT2: A Proco’s very popular distortion pedal, the one used was a later 2010 model made in China by Neutrik.
CE-3: A Chorus Pedal made in Japan in 1987 by Boss. It includes, at its time, a stereo configuration, but we only used the mono one. Phase45: A MXR phaser pedal made from 1977 to 1981, its a simplified one knob version of their well known phaser pedal Phase90, the one used was build in U.S.A. in 1980. E-Lady: A Mooer clone of the Electric Mistress, an iconic flanger pedal from 1975 made by Electro-Harmonix. The pedal used was made in China in 2022.
DL4: A delay stomp box unique in its kind when introduced into the market in 1999. This digital emulator of 16 different type of delays remained unmodified for nearly 23 years. Of the 16 possible delays we used three, Tape Echo, Sweep Echo and Digital Delay. The pedal used is a Line 6 2007 model made in China.
CR6OC: We used a digital reverb emulations of an Orange Crush Pro 60 12-inch speaker combo amplifier. The amplifier used is a 2014 model made in China and it integrates Plate, Hall and Spring reverberations.
