i use single effects units after having used a couple differnet multifx ones. i like this setup better because i get a more consistent tone that to me makes my sound more recognizable. multifx (imho, some people like them) make you sound like everyone else because that is what they do, model other sounds. especially the new ones like the rp2000 and gt-3 and stuff that try to model all these different amps, they do too much in my opinion. i prefer to keep a few good stompboxes and a couple good amps to run through (one clean, one for lead, i use a pan pedal to switch between)

that's my thoughts...
