I have a Mesa F-50 Combo and an Ibanez RGA 121H with an Invaser in the bridge. Currently I use the Metal Zone MT-2 through the clean channel to get that really thrashy, ripping kind of tone for riffing. My only problem is that it lacks some definition. Single note riffs are great and chugging is great but chording just gets lost. So what should I do? The reason I don't use that gain channel is that it lacks the trebly thrash sound I'm looking for. Options: Keep the metal zone Mod the metal zone Get a Metal Muff Get a treble booster for gain channel Thoughts gang?
