Fender amps are better than Marshalls...
Truth. I played through a 2x12 50W Marshall combo for years and it was always the crappiest sounding amp on the stage. But I couldn't afford to replace it (because no one wanted to buy it).
Humbuckers suck and single coils rule.
As a kid I was a DiMarzio user, the Super Distortion and the Super II. When I finally plugged an old Junior into an amp I thought, "Oh, so
that's how guitars are supposed to sound!"
Nobody can hear the difference between silicon and germanium transisters.
I think you're right about that too. But you can certainly hear the difference between a germanium transistor fuzz in a cold room and a hot one. But then germanium transistors were never known for their consistency.
It's funny you should say, "No solid body electric is worth more than five hundred bucks."
I started to set up a page that shows guitar prices from the 50s, 60s, and 70s (it stops at 1966 at the moment, but I have a lot more price data to add), and when you click a price it pops up a window with what that price would be today, adjusted for inflation.
According to the inflation calculator, in 1951 just the
case for a Telecaster was $400! The guitar itself, $1,875. I don't know if that one is a fair comparison since there wasn't much of a solid body electric guitar business in 1951.
A '59 Les Paul Standard sold (or didn't sell) in the showroom for the equivalent of $2,335 in today's dollars. $42.50 ($375) for the case.
Which is all to say that solid bodies from the big names have always been expensive. Have they always been overpriced? Probably. The only new Gibson I ever bought (until 2012 anyway) was a Les Paul Deluxe in 1980. I paid $800 for it ($2,419 now). But like I mentioned, four years later I bought a '60 Junior for $300 ($730 now), so maybe the value of "new" was as out of whack then as it is now...
