The Pedal Power 2 Plus is a power supply unit that can provide up to 8 lines of power to effectors that operate 9V. Each output has an 8-channel fully independent power filter, short circuit protection, and stabilized power circuit, and is designed to provide a stable DC output for each output. The biggest feature of the pedal power 2 plus is that the DIP switch on the back allows the 4 system to support output up to 12.3V. In addition, the other two lines are compatible with the power supply of high current consumption units such as Line 6 pedal effects (DL4 etc.). Furthermore, the remaining two lines can be adjusted to the DC output voltage from 4V to 9V. This is a function that simulates the voltage of the battery and can change the tone of fuzz or distortion using a transistor or OP amplifier.
