Have you ever heard someone say their effects pedal sounds better as the 9V battery gets old? This little space-saving box is designed to emulate that dying battery consistently, using your existing 9V power supply!
Circuits behave in interesting new ways when the power supply begins to fade. I have found new tones from Fuzz pedals and glitchy repeats from Delay pedals. Experiment.
No additional cables required - all you need is a “Boss-style” 9V DC power supply and your pedals.
