I'm a huge Rhoads fan. I remember the first time I heard Randy - now I had started playing guitar the year before VH1 dropped. At that time we were all so into Kiss, Queen, Rush, I mean learning something from Lifeson was like you had conquered middle earth or something back then.
Then Ed drops and immediately to all of us, he became the guy, the guy that took over from Jimi in the hierarchy. He was literally so advanced nobody had a clue or hint of what he was doing. Thing was though it was all about the playing, none of us back then really thought about the guitar tone(s) of any player. Brian May's tone sounded different from Scott Gorham who sounded different from Ace who sounded different from Nugent who sounded different from Schon who sounded different from EVH. It was all about the playing and it was all good to us. I mean the recipe was simple, a Marshall or decent amp, OD pedal and do your best back then.
Then Randy hits and for me as a player, changed my path. I was content being the Rhythm player in my little bands at that time. Rhoads hits and it would be 25 years before I would share the guitar spot with another player. Still though, at that time in 1980 tone was not a factor to any of my friends that were players.
Really from my recollection tone didn't become a factor in my orbit of friends and fellow musicians until the whole LA thing hit hard in '83. Suddenly it seemed everyone was scrambling for their own tone myself included.
Anyway all this thesis aside, really no comparison after the fact in EVH's tone and Rhoads. Looking back I loved how Rhoads sounded on Diary, still do but Ed's tone speaks for itself as it's essentially spawned an entire amp industry. I wonder how Rhoads would have evolved both in his playing and his gear - would have been interesting. I know this in my old age, I am truly grateful for getting to experience all these players as they hit first hand. May, Rush, Lizzy, Journey, EVH, Rhoads etc.. first hand as it happened. I can truly say from the time I picked the guitar and tried to learn from all of my influences till about the early 90's was the most fun I ever had as a player.
