Type 2 Flex cables are red and fitted with a center positive 5,5/2,1mm DC plug. This standard is less popular but also widely used in older or positive ground pedals as for example the ’69 Pedal, Soulbender or Octafuzz from Fulltone or Voodoo Lab’s Proctavia. Red Flex cable should also be used for Moogerfoogers, Radial Tonebones, Effectrode, some Diamond pedals, Blackstar for 22V DC or few Empress and Kingsley pedals. With a longer 12 mm barrel for pedals with recessed power sockets or other special needs.
