So I'm on the lookout for a portable low wattage head. The only GK amp I could find to demo was a MB Fusion 500 in a store and absolutely loved it. I didn't find anything earthshatteringly amazing happened when I brought up the gain though, which correct me if I'm wrong is where the tubes would start to make a significant difference. This made me wonder if the MB200 would be a better fit for me. I definitely don't need the extra 300 watts and if the tube pre at low gain is similar to the solid state one in the MB200, it seems like this would be the case. If anyone who has tried both could share their thoughts on how they compare it would be really helpful. If I liked the MB Fusion am I likely to like the MB200, or are they totally different beasts?
