The D’Addario 9V Effects Pedal Power Adaptors 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 adaptors 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 adaptors are indispensable to have on hand when playing live, in the studio, or at home.
