Si mes souvenirs sont exacts ,Boss a ete oblige de changer de nom car la denomination "super distortion" appartenait a une autre marque, DiMarzio, et l' a renomme en V2
RIen ne change sauf le nom
The first DF-2s was labeled “Super Distortion & Feedbacker” while the later ones was called “Super Feedbacker & Distortion”. DiMarzio had already registered the name “Super Distortion” so Boss was forced changed the DF-2’s name. The change took place around serial number 500000 (January 1985). Production moved to Taiwan late 1989 and was modified for the PSA adapter from early 1991.
