Well, after playing my Trem o verb for 16yrs, and lurking around the Mark V page (as well as the Rectifier page) I broke down and bought the MV! Bought it 3 hrs before I had to leave for a gig and used it that night! I actually spent time on the settings that were suggested here and found some I really liked! I play mostly Top 40 dance rock and some classic rock and I'm liking what I'm getting so far! I followed the suggestions for the effects loop here and it still sounds like someone put a blanket over the amp! Haven't heard a good fx loop from Mesa yet! Ill probably throw an EQ in the loop to bring back some presence but over all this amp has a great tone and I'm finally happy with a different amp other than my ToV! Thanks to all the posters who posted their settings and advice! Be seein ya!
