Okay, I just finished reading about 200 pages after searching and picked up a lot of great info, but also the more I picked up the more I got confused. I'm 45, pure hobbyist with a crappy lower back. I love the GK sound, so I'm going Combo. So, just between the MB115 and 210, I'm wondering about differences in the tone. I'm looking for that clean, crisp GK punch, I'm playing a Ray and probably won't be doing any gigging larger than small clubs. I've read a few of you commenting on sound change after break-in, so I'm a bit leery about what I'd hear at a shop, compared to what you guys are hearing after a month of owning. I do like the idea of expansion with the 210 and if there's little difference in tone between the two, I'd probably lean that way. Please help lay this out, since nobody has them in stock until June, I want to decide so I can try to find a promo before then.
