I have thankfully upgraded from the CB-700.
but for soooo many of us in the 70's and 80's this was the first kit we had!! And Camber cymbals...
I lucked out and got to start on my dads 1955 Ludwig, and still use it to this day. Though back in the early 80's, it was NOT the massive, arena rock monster that all of my idols were playing, so back then, I did not appreciate it as much as I did as I got older.
I did get my fervent allegiance to Zildjian from dad, and have always and only ever played Zildjian because of this
I got my own high end kit in 1994 - Pearl Master Custom Maple, and have used that as my rock kit ever since. Not really because of brand allegiance, but because I have never had enough disposable income to buy another kit, and have (on purpose) never needed to. I bought the Pearl as my "last kit I will ever need" kind of set up and was influenced to buy it because I loved the sound of Pearl marching drums.
The only other brands that have really left me considering another kit purchase would be the Tama Starclassic line and Ayotte custom drums.
