Hey guys I’ve got a question about pedals with charge pumps. I know there’s certain pedals out there that will run at both 9v and 18v. My very basic understanding of a charge pump is that it basically bumps up your voltage from say 9v to 18v. Is the purpose of this to eliminate having to have an 18v power supply. If a pedal with a charge pump is fed 18v does that mean it’s putting out 36v and frying everything. An example that comes to mind is the integral preamp. The TC integrated preamp I’m told can handle up to around 30volts. Is this because of the charge pump.
