I'm trying to figure out if I'm having trouble with my amp, or if I'm just expecting too much out of the little thing. It's driving an ampeg svt210av cabinet. I have a mid to low end logitech 5.1 system hooked to my computer. If I run a bass straight into the amp (active or passive) I have to pretty much beat on the bass to keep up with the tunes on my puter. I can get it pretty loud if I put my vt bass deluxe or my gt6B inline and crank the gain, but then I get more distortion than I want. I have hooked up a second cab (8 ohm 110) and haven't noticed much difference in volume. I don't have another amp to try :[ It should be able to easily out perform a loud stereo right? I can't imagine this thing being useful in any band situation except maybe acoustic :\ My old hartke 3500 into the same 110 was LOUD and would hold up to a drummer and a guitarist. I know thats a lot more amp but not sure if it would be enough to make THAT much difference. If I remember right, the mb200 is 150 watts at 8 ohms, the hartke 3500 is 240 at 8 ohms. Obviously a lot more, but enough to make that much difference?
