9V Voltage Inverter


In goes +9V, out comes -9V. It really is that simple.

NEW – Interactive B.O.M Helper

We include a standalone HTML file with each of our boards that helps show you what parts go where (find it in the “Build Docs & Extra Info” Tab)- just extract the zip file to a folder and open the .html file in your internet browser. You can use the table on the left to tick off the parts as you source them / add them to the board – we found its a very handy and a big shout out to Interactive HTML BOM Plugin which is a free plugin on GitHub used to generate these.

This dinky little daughter board will allow you to easily convert any existing positive ground effects to (daisy chainable) negative ground.

De-solder the supply and ground wire from the existing board, and solder to this board, then take a couple of new wires from the -9V output and ground connections on this back to the de-soldered pads on the effects board.

Really handy, really small and a quick job - now your positive ground pedal will run from your isolated multi power supply, no need for an extra plug!
