HI, I've been around as a musician/guitarrist and are now moving to bass. I have an electronic/rock band and want to upgrade my rig. I'm currently using a Marcus Miller jazz bass with a TC BG250. I'm ok for rehearsals, however, i want to upgrade the combo to a head/cab for the live gigs. I looking for a used rig that i can get for around 700-1000 dlls and i specially want it to be light in weight since i have back problems. I come from a rock world so of course i dig the Ampeg sound, however, i don't want to get the huge svt/8x10 etc and i'm open to a different flavor, but not dramatically different, however i need the sound to be as deep as possible. So my research tells me that i can get the following options and i want your opinion: 1. Markbass Little Mark III and Traveler 12/15 2. TC Electronic rh450 and RS210 3. Aguilar tone hammer 350 and Aguilar GS115 4. Ampeg Portaflex PF350 and 115 Which one will get me that deep, rich low end sound, give me good features, have good quality and mix well with my rocker roots.. thanks in advance for your help.
