i don't think that clip is overgained for the genre...which IMHO is exactly the problem..Rectos sound great when used for rockier/less saturated material but when you start getting into extreme metal gain territory the fizz sets in..
sorry don't mean to hijack the thread metaltastic
here's a track from an album i did last year with a rented 2 channel Recto/OS straight cab..not exactly metal, this was one of the heavier tracks on the album though.

i liked it so much i ended up buying over the recto. not much fizz in that tone i think, but again, it wasnt really in ultra high gain territory. rhythms were gibson explorer w/ duncan JB and a LP Jr with P-90s, think the leads were a valley arts tele with some sort of stacked humbucker. no tubescreamer..
