Guitar effects are commonly used in popular music to shape the guitar sound to fit specific genres or to create more variety within musical compositions. The sound is not only determined by the choice of the guitar effect, but also heavily depends on the parameter settings of the effect. This paper introduces a method to estimate the parameter settings of guitar effects, which makes it possible to reconstruct the effect and its settings from an audio recording of a guitar. The method utilizes audio feature extraction and shallow neural networks, which are trained on data created specifically for this task. The results show that the method is generally suited for this task with average estimation errors of ±5% − ±16% of different parameter scales and could potentially perform near the level of a human expert.
