Welcome Bassican, I have a few Cave Passive Pedals actually. I totally agree with you, they can make a pedal. A great one at that. How good is the G4! I did a demonstration with the G4 and really enjoyed doing so. Everything from Cave has just got the highest quality which some pedals lack, they're also unique and and very versatile. They're different and that's why I like using them. I'll show you a link to my youtube channel where I have a few video demonstrations of some Cave Passive Pedals. Enjoy dude!!
