The D’Addario 9V Effects Pedal Power adapters are an essential tool for the modern musician, eliminating the time and hassle of opening a pedal to install or replace a battery.

For pedals utilizing a 2.1mm tip negative power input, the cables can supply emergency power in case of power supply/battery failure, power pedals without internal battery connections, or provide temporary power to seldom-used pedals. The adapters are also a convenient diagnostic tool to pinpoint pedalboard noise issues by allowing you to isolate power to one pedal at a time.

The power adapters are indispensable to have on-hand when playing live, in the studio, or at home.
