Yes, and no. Lots of multi-effects have a "rectifier" model (I know my rp200 does) but it doesn't hold a candle to the real thing.
My Gear:
American Deluxe HSS Strat
Crate GT212
Vintage '66 Fender Champ Amp
Dunlop Crybaby 535Q
Jekyll & Hyde Ultimate Overdrive
Vintage '74 MXR Script Phase 90
Vintage '77 MXR Flanger
Orange Squeezer (clone)
^ shut up.

Pretty much every multi has at least one Rectifier model. MOST model channel 2 on Vintage mode...which still sounds scooped and heavy.
