I've been playing my GK MB115 combo now for a few months and have been enjoying it quite a bit. Tonight, I finally had an excuse to drag out the MBP115 powered cab with, as I was playing a bigger stage than normal, so I thought I'd write up bit of a review for both. The GK MB115 combo is well built, and boy is it light. It sounds good, but it doesn't sound as "GK" as I would like. I have had lots of GK amps / cabs and this is a bit different - it's not quite as punchy / grindy, and puts out more low end set flat. I roll off a chunk of lows and some low mids to get it sounding right. But it does sound good, and it's a pretty loud 200 watts. Covers me in 95 percent of my cover gigs. It's a professional piece of kit and it seems like it will hold up to regular use, but there is no ground lift on the DI, which is pretty irritating, and the knobs can get bumped in transit, which is mildly annoying. It is a serious bargain, though, and I probably would replace it if it broke. The MBP115 powered cab is likewise well built, and light. I like the design - it seats the combo nicely and the two stacked seem stable. Adding the MBP115 certainly adds oomph, but not as much volume as I would have hoped. Don't get me wrong - it's louder than the combo on it's own, just not as much as I expected. I will admit, though, that I do like having a speaker closer to ear level. I am not sure how often I will use it, but when I do use it I will enjoy it like I did tonight. This is also well priced, but I am not sure I would buy again, if it crapped the bed. Hope this helps anyone interested!
