Ok. I want to get that cool lead tone that guitarists such as John Petrucci, Van Halen, Slash, Vai, Satriani and the like get. I am pretty sure it has a lot to do with reverb. The amp head I am currently using has NO built-in reverb and it is pissing me off. When I play through my rhythm guitarist's 5150 my leads sounds amazing...but he also uses a BOSS digital FX board. The sound that I want is pretty simple...not a lot of congested and superflous FX....can this be done just as well with a BOSS MT-2 Metal Zone (which I am using right now) and a BOSS RV-5 Digital Reverb (which I am thinking of buying)???¿¿¿

If so, can anyone recommend any cool settings for either/both pedals for leads?
