This happens a lot: The quality of sound during sound check is awesome. Curtain goes up and sound quality goes down. Most noticeable for me is guitarist's sound. He swears up and down that the patches are the same but it sounds like mush and general garbage a lot (enough for me to post here...). Here's some background: Hard rock, 4 piece: guitar, bass, keys, vox and drums. We don't bring our own PA or sound guy, and everyone let's me have input on mixing. We play churches, outdoor festivals, indoor stuff... all kinds of equipment levels from garbage systems to high end pro-level festivals. Even when we played the Air 1 Stage at Spirit West Coast, we got the same result. We go direct into the board to make it easy on the sound guy (they loves us for that). I assume, it's the energy of the playing in the gig versus the nonchalance of sound check(?). Anyone else ever get this? The latest example: Played on Saturday. Medium-quality sound system (good Mackie board and older JBL SP-15's and Mackie subs) Sound check before the game was great. We played post-game 4 hours later, with no other band opening for us, and got garbage. Should we power down with 4 hours before curtain?
