DISTORTION: Boss Metal Zone, Pro Co Rat.
OVERDRIVE: Ibanez Tube Screamer Classic, Boss Blues Driver, Boss Turbo Overdrive. Add a compressor in front of any of these and you may not need a distortion pedal at all.
DELAY: Boss DD-6 or DD-20
CHORUS: Boss chorus, or maybe MXR Flange instead. Also a Digitech Whammy when set to the "Detune" setting actually makes a pretty good chorus sound, and you get some really cool pitch shifting effects as well.
FUZZ: Dunlop Fuzz Face or Electro Harmonix Big Muff.
The Boss GT-8 & GT-10 are awesome multi effects pedals, and have the sounds of many classic Boss stompboxes, as well as modeling to simulate the sound of other brand pedals and guitar amps. Awesome value and great sound!
