Thanks, those two are probably the best to compare since they are both 15" and that is what I am thinking of getting. I am retiring and I am picking up the bass again after, gulp, 35 years of making a living and working too much. I try to play like before and my hands hurt! but anyway...
My 1973 rig was a Sunn Concert Bass Head and an inverted horn twin 15"s. That was a monster set up and worked well everywhere. Sold that but kept my Ric that was customized with a precision pickup.
When I went to GC to try out combos, I went to the Markbass first. Sounded great! Then I plugged into the Rumble v3 100. Immediately, my wife who was standing about 15" away (from both) said wow! What a sound! Since the Markbass seems to be a standard for pros, I want to know if my experience was just because we were "in store" or if I would get that same feeling at a rehearsal or gig.
In Italy no one has a lot of room to store things and multiple set ups won't do. Fender is expensive there. A Markbass JB Players combo and the R 200 are the same price. I think that because I can use the Rumble to practice (CD in and Headphones out), play at home, have the power enough to jam with others including a drummer and have the flexibility to add an extra cabinet when needed the Rumble looks like a winner but I want to hear from others first. I can also get a 121H or 121P used for that same price point.
Thanks for the input.
