I'm getting ready to buy a much needed bass amp for a new group I'm going to play with. I'm looking at two possibilities, and I'm pretty sure I'm sold on the GK MB112 II but I have a question for you guys already using one. We are not going to be playing loud or in big clubs, but I definitely need a low end thump to my sound. I play two fingered, 4/4 rock bass. I like a big bottom end. Will the GK MB112 put out a nice bottom end thump? I know it's only a 12" speaker but I've heard some that thump hard enough that you feel it in your chest! I like the weight and the idea that they are manufacturing in the United States. Go GK! Thanks in advance for your answers.
