General Operation

The ES-9 is an external 9 Volt battery supply for EMG Pickups. If you have an instrument that doesn’t fit a battery, or you don’t want to install a 
battery the ES-9 is perfect for you. Using a stereo cable to bring +9 Volts up the Ring contact to the instrument you can power your instrument 
easily. The ES-9 also has an external DC input for powering your guitar. See the notes on page 2 about using an external DC Supply.  A standby 
switch also makes it convenient when changing instruments by shorting the input to the amplifier. In addition, the battery and external DC 
supply are protected by a resettable fuse in case the input/output are reversed. instructions are supplied to help you learn about using an 
external supply as well as the options available.
