I just bought the PS 04 Palmtop Studio, it rules. It's got a drum machine, bass machine, multiple track recorder, it's got a shitload of different amp model sounds, its got 90 some odd guitar effects, five different drum kits to choose from, its got everything I'll ever need to do a full length album in the comfort of my own home. And when you record any track, you can choose what type of sound as in, full sound, live sound, soft, power ect... I could go on for pages and pages about the shit this thing has built into it. It's literaly everything I need! For $400.00!!! I don't even need other band members with this thing for crying out loud! Added to my GX1200H Crate full stack and my Jackson DK - MGT guitar with EMG HZ pick ups, I don't need anything else now! Isn't that kick ass? I don't even need to worry about upgrading cause my equipment %100 up to par to my standards (wich is quite high). The PS 04 kicks ass, you all should try it! No, you all should go out and buy one! It's a full recording studio that fits in the palm of your hand!
