Abstract: The invention relates to an apparatus for storing and generating sound effects with the help of analog devices (5, 6) when playing a musical instrument. The apparatus comprises one or more positioning motors (4) which can be connected to potentiometers of the analog devices (5, 6) by means of shafts (7). The apparatus further comprises means for storing and retrieving the settings of the positioning motors (4), a specific setting of the positioning motors (4) being used for generating a specific sound effect. By connecting the apparatus to many different types of analog effects devices (5) and tube amplifiers (6), the apparatus according to the invention allows specific sound effects to be preprogrammed and stored which the musician can easily retrieve as required, without having to make adjustments to the analog devices (5, 6).
