Recently, I bought a GLXD16, played with it in my house for a little while to get used to all the settings. The other night, I pulled it out and used it in a show with my gig rig at stage volume. My bass sounded awful, and at first I couldn't figure out what it was. Around set two I realized it was probably coming out of my GLXD16, so I unplugged it and used my trusty chord the rest of the gig. When I got home I went through the settings and realized that the default Audio Gain was set at +20. DOH!! : Brain fart: totally my fault for not checking. Everything sounded great at low volume at home and at rehearsal, but at stage volume everything crapped: Lesson learned.... rolled down audio gain to +0, will actually check the gain during next gig at sound check. This got me thinking... What do your GLXD audio gain set at?
