Abstract: An expandable collapsible pedalboard for supporting effects pedals or other audio processing units features a first section having a first platform, and a second section having a second platform of lesser elevation and width than said first platform. The second section is telescopically mated with the first section for sliding movement in a longitudinal direction between a retracted position placing at least a majority of the second platform beneath said first platform, and an extended position reaching outwardly beyond an end of said first section to reveal more of the second platform from beneath said first platform. Multiple pedalboards can be laid out side-by-side and fastened together to collectively form a larger modular pedalboard. A hollow space delimited between side walls of the second section can accommodate one or more power supply components for the effects pedals or other audio processing units.
