The Kertsopoulos pneumatic foot pedal guitar is designed and constructed by Yorgos Kertsopoulos as a prototype in 1988. The functions of the levers, the pedals, the air cavities and the pressure gauge are of a dynamic nature, meaning that there is no electricity involved but only pneumatic technology. In this sense the instrument possesses all the materials and concepts of design of the traditional guitar making so it could have been made 300 years ago. It is a modern concept respecting the traditional making.
