HI! Anyone out there is the vast bass universe ever tried Mark Bass Amps (www.markbass.it)? They seem like great amps, I am interested in the TA503. I did a search in the forum, but I couldn't find much info. I am especially inteested in the 4 band parametric EQ and the 8.6lbs. I'm thinking of getting something along these lines an paring it with a LDS 2x8 for a nice killer lightweight rig. Anyone use Mark Bass stuff out there?
