Transistors don’t have a sound, circuits do. Old Ge transistors have attributes that are difficult to nail down by model number. That’s why people have come up with tests, like RG at Geofex. Two transistors of the exact same model might end up making two very different sounding pedals. I’d worry more about who/where I’m buying germanium devices and less about specific models. Reputable sellers will sell you something useful, eBay pirates will sell you anything labeled Ge, regardless of usefulness relevant to pedal building, just to cash in on germanium mania.
