Before i bought this little FANTA DI Box i thought that the only real method for recording is micing te spaker. After reading several reviews in the net, i decided to buy this little box. The way of sound is Amp - FANTA DI Box - Cabinet. You connect the FANTA Di Box via a XLR Cable to your mixer or, in my case, dircetly to the soundcard. The sound is really great. I made a challenge between the fanta box and a sm57 mic recording and i can say, i cant hear great differences between both. So, this is an easy way to record very quick.
I bought this initially for recording my amplifier in my project studio, it produces a really nice realistic sound and is exceptionally reliable in use and reliving knowing that I don't need to constantly be worried about microphone positions. The F.A.N.T.A is a also equally usable live and so far has proven to be fantastic for sending to my monitors and even sending to the front of house as it is much easier to control than a microphone when taking in to consideration the full mix.
