    Hey folks,
    I need some insight on how to take a circuit I have that runs off 9v and basically tweak it to accept a 12v power supply.
    I'm wanting to convert a guitar pedal design and configure and turn it into a Eurorack module.
    Anyone able to offer a little help?

    Thanks in advance,
    -Ryan

    Check the specifications on the components, some might work on 12 volts just fine.

    Another option is to use some kind of converter to step down the 12 volts to the 9 volts. Sometimes diodes are use for it, if each diode takes 0.7 volts, a few diodes in series will reduce the voltage by 0.7 volts for each diode, but not effect the current so you can get close to 9 volts you need and have current that you need.

    (4) 1N4001 diodes or an LM7809 chip
