i used to be real big on the multi-fx thing, but i've since gone back to individual effects units (pedals and a couple rackmounts) the multifx will give you way more options which is great if you have to play many different styles, but if you want to define a sound that is yours i think a couple good amps and a few stompboxes is the way to go.. multifx are good if you want to sound like everybody else....
