Was wrong about using preamp tubes in my fuzz pedal until a builder set me straight

I always thought throwing a 12AX7 tube into a DIY fuzz build would make it sound way better, like instant vintage goodness. Then I talked to this older guy at a local gear swap meet in Portland last month, he builds clone pedals for fun. He told me tubes in fuzz circuits are just using a couple of the pins to clip the signal, not actually amplifying anything. He showed me his simple two-transistor fuzz and it sounded just as gnarly as any tube-loaded build I'd heard. That hit different because I realized I was chasing a gimmick instead of focusing on the actual circuit design. Now I'm looking at transistor options like old germanium ones instead of wasting space on a tube I don't need. Any of you had a similar wake-up call about a part you thought was mandatory?

Got absolutely wrecked by a similar myth about using NOS capacitors in everything. Bought a bunch of old paper-in-oil caps from some vintage radio guy on eBay, spent like 60 bucks on them. Stuffed them into a overdrive pedal I was building, spent hours soldering those big clunky things in there. Sounded completely dead, like someone threw a blanket over my amp. Then my buddy who actually knows what he's doing points out those old caps leak DC like crazy and drift out of spec over time. Swapped in some cheap modern film caps and suddenly the circuit came alive. Now I laugh every time I see someone swear you need specific caps or wires or whatever, it's usually just placebo hype from internet forums.

70 bucks on some "audiophile" power cables for my stereo amp back in 2015 because some forum swore they'd clean up the bass. Hooked them up, listened for an hour, couldn't hear a single difference from the stock ones I pulled out of a drawer. Ended up using them as shoelaces for a joke at band practice, and honestly they worked better for that.
