Clip: Randall ISO V30 vs gt75

Was the first one the 75? They both sounded pretty close to me except the first one had a little more high end. Cool song.
 
they both sound decent but seems overloaded compared to a the typical miking one speaker in a 4x12. cool riff.
 
I guess I should explain. By overloaded I mean that there is too much speaker breakup in both clips because only 1 speaker is handling the load of the amp. Typically, you mike only 1 speaker in a 4 x 12 cab but the load is being handled by 4 speakers so there is less speaker breakup. The "overloaded" speaker has too many mids and diminished bass response in comparison one speaker in a 4X12. Hope that clarifies the point a bit.
