POWER

The Fat Sandwich Distortion can be powered by a single

9V battery or with a Dunlop ECB-003 external DC power supply. 

The power input is a 5.5mm x 2.1mm jack with the positive 

voltage on the outer sleeve. Using an external power supply

will disconnect the battery. Disconnect the input jack to

preserve battery life when not in use. The pedal will lock

into bypass mode when it is time to change the battery. It

also includes power protection circuitry to prevent damage

from AC power supplies.
