enamel paint on metal
edit 7/10/14- Please note I painted a couple of guitar pedals as an experiment (including this one) and to accommodate a special request several years back.
Due to the high toxicity of the enamel and the high level wear and tear the pedal gets by nature, I choose not to do this sort of work anymore. I cannot ensure the images will remain intact after years of heavy use. There will be updates soon on a new gallery where current work will be displayed.
