I'm not sure if it's actually called an auto tune or tone or whatever but my brother sings and he loves the way T. pain, KanYe West, and (sometimes) Lil' Wayne sounds when they use those things. The cost doesn't matter at all. Actually, the more expensive the better because I want to surprise him with it... but I want a trial of some sort to see if it's good... I haven't found one yet so if you know of any, please share the links!! Thanksss
