Hello, good sirs! I play in a rock band (2 guitarists, singer, keys, bass and a sane drummer). We won't be gigging much, it is more of a fun thing, we just like to play. I currently have a GK MB-112 combo (version 1). I like the sound of it, but it leaves something to be desired volume wise. I would like to stay with GK (always been happy with their gear). I would like to spend as little money as possible while maintaining similar tone and improving volume. I am thinking seperate head and currently one cab, as this will be more flexible for future upgrades. Used is out of the question (can't find anything here in Slovenia). So here are three of my ideas: 1. RB400IV 115 NEO 2. RB400IV 212MBE 3. RB400IV 112 NEO Since all of the cabs are 8ohm, I am only using 180W of power. Will any of the rigs actually be louder than my current 200W combo? I am thinking the first two might be louder because of the larger speaker area, and hoping 112 NEO is maybe louder than the speaker in my combo? Any other ideas in similar price range? Thank you for your help (and sorry for all the funky spelling)!
