I picked up the little MB10 last fall. I had several Christmas gigs with a piano player friend of mine and wanted something really small and portable just for those duo gigs. While I was at the store down in Santa Ana, I tried out the MB12 and was very impressed. Larger than what I was looking for but much nicer sound than the 10" version. I don't think you could go wrong with either, but that MB series sure is nice.
