yes, youll need one....but if you are looking at the Delta 66, put out a few more $$$$ and get the Delta Omni Studio....comes with the Delta 66 pci card plus 2 awesome preamps and alot more routing options........
Hey Rapper!
I got the Delta OMNI package for $399.00 at guitarcenter. If your budget is $300.00 then you should try to invest another $100.00 and get the package, that way you won't have to worry about a preamp. The OMNI breakout box also acts like a mixer.
BY the way, you can also bargain at some stores and try getting it cheaper. Just tell them you are on a tight budget.
Good luck and tell us what you get
