Box made a number of effects pedals in the 1970s. These pedals
were housed in heavy metal cases with bright colored paint
jobs and intersting names such as Spaceship Flanger, Cosmo
Chorus, The Choker, Rotophase, Tubemaniax, and Mysto Dysto.
The paint colors seem to fade and change over the years from
looking at photos of different pedals.
