I've been seriously considering music production for a fair amount of time. I went to guitar center and checked out turntable kits, I don't know much at all about turntables and mixers or anything. I was wondering if anyone could suggest a good way to learn how to use turntables and mixers for hip hop use, scratching, mashing, etc. I was also wondering if anyone knew of any relatively inexpensive kits that include 2 turntables, a mixer with effects (i.e. echo, flange, etc), you know something with a lot of options at a relatively low price. Preferably including speakers... and any advice on mp3/usb/iPod turntables and CD turntables? All help is greatly appreciated!!!
