Type 2 Flex cable is red and fitted with a center positive 5,5/2,1 mm 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 22 V DC or few Empress and Kingsley pedals.
