The Power Pump is a versatile power supply board that allows you to provide different voltage levels to your guitar effects pedals. It can convert a standard 9V supply into an 18V supply, giving your overdrive pedal more headroom. It can also provide a -9V supply for posi-ground fuzz pedals, allowing you to power them on the same daisy chain as your other pedals.The Power Pump can supply around 20mA of current, depending on the integrated circuit (IC) used. It also features an optional starve control on the -9V supply, which simulates the sound of a dying battery.It is important to note that due to its relatively low power output, it is recommended to use one Power Pump for each circuit that requires power. If you are unsure about your pedal’s power consumption, it is advised to check the specifications. The Power Pump is not recommended for battery use.The starve pot, if used, is conveniently board-mounted, minimizing wiring and making it easy to mount the Power Pump in an enclosure.
