i have played dual rectos and recently roadster mesa's...and love the tone and thickness i get with these heads...but am tired of carrying all this stuff around....i have heard tons of clips but nothing thick and heavy,,,all just very wet and weird sounds...can this thing get a thick mesa type tone and yet be responsive?.. for me the effects are just frosting on the cake,,but the meat and potatoes has to be a great distorted sound...most clips i have heard sound thin..that may be because the user wanted it that way who knows...i really am looking for grail in a box but have not heard proof yet...the marshall tones sound good but nothing thick and heavy...not metal either..something like the sound from the band RA when they redid every little thing she does, by the police : hell even something like the nickleback recto sound would be ok...if i could get some air moving..hehe
