Overprotective Parent (I'm 18 & Moving Out)

 Exact same circuit as the original but with the added onboard charge pump. Circuit will prevent damage from over voltage and is resettable/reusable over and over again. Refer to the original for more information. 




Overprotective Parent

 This is one of the coolest circuits I've been able to wrap my head around. An overvoltage and polarity  protection circuit that wont require the any parts to be changed or re-soldered due to misuse. The only pedals I've had to fix for people were broken because their "friend" accidentally plugged in the wrong power supply and fried some internal components. This little circuit will prevent those parts from getting fried, and will also save the hassle of having to repair it. What is commonly referred to as a 'crowbar circuit', it baffles me that this isn't more commonly implemented. 





Piggyback Pair

Germanium transistors are becoming more and more scarce and the ones that you do find aren't great options for the classic fuzz circuits...
