Colin's echo machine is one of two reproduction machines, of which I have the other one. they took 3 years to develop, and there were 7 prototypes. The prototypes have all been scrapped. The electronics are today's technology, but the circuits closly follow the Vox/Meazzi unit. We sourced and used many vintage Meazzi parts in the project. There will be no more of these produced as the project was exclusively for Colin. Colin still has the Atlantis unit which he currently has with him as a spare machine.
