Playing my first outdoor gig in a few days. Need some gear reassurance. I rehearse with and a Shuttle 6.2 (600W) + Epifani UL110 & UL 112. It's plenty loud enough indoors and I can easily overpower a drummer. I have an outside dig coming up. Should I have any concerns about moving enough air with this rig? The drummer won't have any more assistance than a kick drum mic, so as long as I can keep up with him I should be fine. I have other (bulkier, heavier) cab options, but would prefer not exercise them if I don't have to.
