OD type pedals that work with the Mark V from my experience and opinion:
Channel 1 - Clean - Kanji or Eternity (like a 4th channel) they have their own voice which works well with Fender type cleans
Channel 2 - Crunch (no EQ) - Analogman Prince of Tone (boost mode) pushes it into a great hot rodded Marshall tone ala VH, Dokken, Ratt etc
Also Xotic BB Preamp works well in either Channel 1 and 2
Channel 3 -with or w/o EQ - pure magic - nothing needed
General use - Xotic EP booster (adds another dimension of warm/fullness)
Pedals that did not work well (again my opinion)
OCD (kinda harsh)
Timmy (gritty)
Maxon VOP-9 (kinda dark and has a weird clean signal blend )
RockBox Boiling Point - has it's own thing going - could not dial it in correctly as a boost or standalone
CMATMODS Signa Drive - like Rockbox but mine was very noisy
