I just started working with the Numark 3002X, it cost me 2 bills. Some people dont like Numark, but i have to say that im not "some people". Its a 3 channel mixer, so its kinda bigger than most skratch mixers, but it aint huge. The crossfader is made for skratching. It allows you to adjust the fader into 2 settings. one for skratching and one for mixing. Its really useful. And this thing has awesome kill switches that arent too close to the fader, just in the right spot. You can kill the bass, high, or mid, and i mean you can KILL it.
That dude was right about matching the snares, what you gotta do is get the snares in sync and kill the bass, then slide the fader over. Its not as simple as it sounds, so you are going to have to PRACTICE .... practice alot ..... i bought the Numark beetkeeeper to help me with mixing. but im taking it back in exchange for more vinyl. I learned that there is no substitue for practice.
