The 1 SPOT Combo Pack consists of a 1 SPOT 9V DC power supply, Multi-Plug 8 Cable, (2) Battery Clip Converters, (2) 3.5mm (1/8) Converters and an L6 Converter for Line 6** modeling pedals. The 1 SPOT is the original 9V DC adapter that only takes up one spot on your power strip. With the ability to handle up to 1700mA, the 1 SPOT can power your entire pedalboard. You can even use the 1 SPOT anywhere in the world without a voltage converter because it automatically converts voltage worldwide. No need to worry about AC hum interfering with your sound either...the 1 SPOT is one of the quietest power sources you can buy.
