The RoadRage2019 is a compact utility that allows you to obtain multiple voltage supplies from a single 9v power supply. It can deliver 15v (or 12v) regulated, 18v unregulated, and -9v.

There are several applications for the RoadRage PCB in pedal building. It can be used to create a -9v positive ground supply for PNP fuzz or other positive ground circuits using a regular negative ground 9v power supply. It can also be used to generate a 15v or 18v supply for an overdrive, providing additional headroom or dynamics in some OD circuits. Additionally, the RoadRage can serve as a prototyping rig for circuit design and breadboarding.

The RoadRage has limitations when it comes to current supply and efficiency. The LT1054 charge pump, which is recommended for use with the RoadRage, can supply around 100mA of a pumped up or inverted voltage. This is sufficient for many analog circuit designs. The alternate charge pump, TC1044SCPA, is less powerful with a maximum current of around 20mA. However, this limitation is still sufficient for many overdrive circuits and all PNP fuzzes. The TC1044SCPA is also more affordable, costing only $1 compared to the $3 price of the LT1054.

If you plan to use the RoadRage for multiple projects, it is recommended to have both types of charge pumps available so you can choose the appropriate device for your application.
