Hey guys, I'm running a Gallien Krueger 700RBII head with a 8 ohm Avatar 210 cab right now and I'm looking to put another cabinet into the mix. I feel like I'm pushing the cabinet too much and I'm getting farting noises out of the cab. Before it's too late and I do serious damage to the cabinet(hopefully it's not too late), I want to add another cabinet. I was looking into another avatar 210, Gallien Krueger Neo 115, and a Gallien Krueger MB series 115 or 210(I'm not even sure if these mix well with heads other than the fusion series). Weight is an important factor as well, if someone can confirm the story on the MB series cabinets, if it'll mix well with the 700rb, it'll make my decision easier. Any help would be great, I'm not looking to spend more than $400 on a new cabinet right now. Thanks a lot!
