The standard black DC jacks we use in all of our effect pedals. These are 2.1mm DC Power jacks, with enclosed frame (the nut is mounted from the inside so it’s not visible from the outside of the effect pedal). These black DC jacks have three lugs for ground, positive and positive from the battery. They have an internal switch so if no DC adapter is connected the pedal is powered from the battery, and as soon as a DC adapter is plugged the DC jack automatically disconnects the battery. It’s the perfect DC jack for any diy effect pedal project.
