Abstract
The aim of this thesis was to create an effects unit for an electric guitar. In contrast to many
mainstream formats of effects units, the intention for this device was to be installed inside of
a guitar. It was designed for digitally processing sound for the possibility to easily change the
effects it can create. As a prototype it was initially created to be able to produce the distortion
sound effect. The content of this thesis will cover the design of the device and it’s installation
inside of a guitar, other similar solutions to this project, and the theory behind the distortion
effect.
