Germanium bipolar transistors with substantial power handling capabilities (100 mA collector current) were introduced around 1952; with essentially the same construction as signal devices, but better heat sinking. Power handling capability evolved rapidly, and by 1954 germanium alloy junction transistors with 100 watt dissipation were available.

Can I choose a different transistor type for a Twin Bender? No.  What is special about powering Germanium fuzz pedals? The correct type of Germanium transistor used in many fuzz pedals are special in that they require opposite polarity power. You cannot power two pedals with different polarities from the same power supply.

Well, for starters germanium transistors have the opposite polarity from most common silicon transistors, like your 2N3904. So you need to swap the plus and minus of your power supply, plus reverse all diodes.. What strikes me as a bit odd on the diagrams in the article is the use of a dual power supply, with both positive and negative voltages.
