I have been mulling around the idea of trading in my 4 effects pedals to purchase a multi effects pedal. I play a wide range of metal from Pantera to Cannibal Corpse to Opeth, any suggestions as to what would be a best buy? My aimed price range is between $299-$499, so try to please keep it around there, thanks!
i personally prefer having around 5 pedals rather than an effects pedal. more customization and such.

line 6 makes some good ones.
if you want the tone of your amp with your pedal, go with a Boss GT series

Ibanez S370 (all custom)
Mesa Boogie Studio Pre
Fender Champ 25se (used to power Mesa pre)
Custom 2x12 cab w/ Eminence Texas Heats
