Converts a power supply's 2.5mm plug to a 2.1mm 'Boss standard' barrel plug.
1 female 2.5mm socket & 1 male 2.1 plug; about 3" long.
Power supplies for Digitech pedals (like Whammy), LINE 6 MODELERS etc., have 2.5mm power connectors. Use this adaptor in a PedalSnake rig to connect a 2.5 power supply to the Amp End of a 2.1 PedalSnake PLine.
NB - LINE 6 MODELERS, when powered by standard 9vDC supplies like the Dunlop Brick need 2125AR and 21RP at the pedal. If the LINE 6 power supply is used, use only 2125AR for the pedal, and 2521A for the supply (at the Amp End of a PedalSnake PLine).
