I'm thinking about picking up a GK MB 210. I previously owned a GK MB115 (grey metal grill version) and it rocked. But I'm thinking of an MB 210 for a backup to my Streamliner 900/Schroeder rig for gigging. I'm not a fan of lugging multiple amps/cabs to gigs so I'd probably never use an extension cab, but I'm wondering why the "new" black cloth grill version of the MB210 (or any of the MB combo series) is 350 watts versus the old gray metal MB210 which was 500 watts. Has anyone compared the two? Will I miss those 150 watts? Have there been other improvements to the new black cloth versions or was it just the appearance that was changed? I'd appreciate any input. Love the MB line. I'm used to a Hughes and Kettner 400-watt combo which is a complete tone and volume monster but it's 64 lbs and I'd like to go lighter (it's for sale if anyone wants a beast of a combo and doesn't mind weight - I'm throwing in a free cart to roll it around.) Thanks!
