for me, my first encounter with Peavey was when the rich American kids from the international school came to my school for concerts and sports. They had Peavey speakers and Reebok sneakers!
Rich kids got Marshall. Or Mesa Boogie.
Interestingly enough, another guitar amplifier company that could be considered VERY premium started in a very similar way: modifying and building their own gear just out of frustration with (back then) existing gear and lack of money: http://diezel.typo3.inpublica.de/history.8.0.html
Actually, Boogie did too: http://www.mesaboogie.com/US/Smith/our_story.html
