the amp at my church seems to keep having issues so i'm thinking about buying a new amp for the church. since i'm a GK man, that's where i'm leaning. i wouldn't mind getting one of the new mb500-2x10 combos but it's a little overkill for the room. we seat about 180 or so. and there's a direct line to the board. this is only used for stage volume ("competing" with an acoustic, an electric, piano, tuba, trombone, french horn and electric drums). having said all that i'm thinking one of the mini 1x12 combos. i have experience with the 200rcb (the head version of the 200mb) and really liked it. but i'd have to go used for that one. since it'll be used by a lot of people, and hopefully for a while, i was really thinking about buying new. so for those with experience with both i have a few questions. - how similar do they sound to each other? - any issues with buying a used 200mb? - is it worth the extra money to get a new 150 vs. a used 200? - should i ditch these two and get the mb2-500-2x10? - is there another amp i should be looking at? thanks for the help.
