how about stompbox na lang sir? for pure, transparent, analog tone.
It depends pa rin sa amp diba sir? I think marami siyang tones na magagawa with a POD HD 300/400/500. Lalo na sa Prog Metal iba pa rin yung medyo compressed na distortion from a high gain amp like a Mesa Mark V, ENGL Powerball, Peavey 5150/6505, Bogner etc... diezel, krank,bugera etc... dami dami hehe.
Just for me tingin ko go for a POD unless maganda na amp mo and you're just going for the effects ng multi then mag analog ka nalang. Anong klaseng prog ba? Dream Theater o Genesis o Yes o Pain of Slavation etc...? So i guess mas ok nga multi kasi makakapag experiment ka din sa sounds. After fiddling with your multi maybe then you could decide afterwards ano ba talaga setup mo sa amps and effects.
Sorry ME-50 pala at GT-6... ako POD nalang. soundwise panalo wag lang sana bumigay tulad nung xt live ko.
