I create my presets in stereo. I work mostly in the studio but, when I play live, I have to convert to mono. I know that SUM L&R can have issues in terms of phase cancelation and other things. I don't use short delays or the enhancer much. So, If I want to go Sum L+R and not have to listen to every preset carefully for issues, are there any rules of thumb or tips you guys can give? What are the "primary culprits" to watch for? I know the smart thing is to give them the "ear test" but time does not always allow and I change stuff up a lot. Also, I fear that issues that may not be readily apparent to me may be moreso FOH.
Thx!
