I used to be a big Technics fan, until I got my 9000Pro.
The reason why I chose this board were the Dance, Disco, Hip Hop, Pop, Techno, etc... Styles.
I play mostly modern dance music from the 80's, 90's and today, including light Rock, Pop Ballads and Pop. Even though I loved the guitar styles on the SD1 the Yammy gave me more variety in the type of music I play.
