I'm in the middle of designing and building my rack rig. My goal is to make set-up easier, make troubleshooting a breeze, end tap dancing, increase sound quality, etc (you know, all the normal reasons for going rack). I've been debating adding a Carvin DCM150 for some stereo or wet/dry applications, but I don't really want to haul around another cabinet and microphones. Besides, the most people I play to is around 750. I think having 1 rack space left to fill is giving me nasty, nasty ideas. Anyway, I've been checking out some pro rigs and seems like very few run mono. The only ones I could find were: Brad Paisley (maybe) Johnny Marr (maybe) what other pros run mono?
