This is version 1 of the Rainbow Machine…..the primary and secondary knobs are reversed and it’s loaded with the “Click” type foot switches instead of soft switches. There’s a slightly sticky residue on the bottom plate from a previous strip of Velcro with a spot of adhesive (from the Velcro strip) that I couldn’t remove. The pedal has few light scratches and dings. The set-screw knobs have cracks in them and occasionally loosen a little which slows down the exploration. Includes the original box, manual and bag but no battery or adaptor. Be sure to check out the other pedals for sale in my shop and heart me to be alerted to future listings.
