Adapting Eurorack circuits as guitar pedals? (12v > 9v power, …

If you want eurorack modules as a pedal, I think there are multiple options depending on the module you are trying to convert. A charge pump could boost voltages from a 9v power supply (but not really as high as +-12v) and a vactrol could do some (but not all) CV stuff. Check the Vac Pak from synthrotek for example.

Step-down 12v to 9v? | PedalPCB Community Forum

Yes, you can put a 12V regulator in the cable. Two caveats: 1) The regulator will dissipate some heat. Most pedals draw 10mA or less. If you power two of those, then the power dissipated in the regulator is 2 * 10mA * (12V-9V) = 60mW + whatever the reg needs to run, usually another 60mW, so 120mW total. That''s low enough that you …
