Tech Tip:Preserving The Battery Life Of Your Effects Pedals
Getting your favorite effects pedal set up onstage only to find that your pedal's battery is dead is a common annoyance of guitar and bass players.
To maximize your effects pedal's battery life, always disconnect any patch cables that are connected to it after each playing session. Why? Because as long as your effects pedal has cables plugged in it's on, and drains the battery.
