My flagship rig is a GK MB800 on top of two Mesa Powerhouse 410s. The cabs weigh a ton and the head looks like a toy on top of them. However, this rig (despite being my "flagship") doesn't get a lot of time on stage these days. Right now that work is done by a GK MB115 Mk II and a GK MPB115 - for a thunderously loud yet seriously light combo rig. The combo rig can't compete with the 810s in terms of raw volume, but the combos get me pretty much anywhere I need to be these days. I would love a chance to unleash the big guns, but gigs that would make use of them are rare for me these days. So combo rig goes on the live stages and cabs wait patiently for their turn to shine again.
