I play with a 16 piece jazz big band. We rehearse weekly in a large but not overly boomy room at a local church. I always bring my Hartke kickback 10 and sansamp bass driver for tone shaping. For years I've struggled to get a decent consistent sound in that room but as of late I've been mostly winning the tone battle in there. The sansamp has become my easy button. So, last Thursday at rehearsal we were arranged a bit differently in the room. My amp ended up back and to my right very close to a wall projecting cross the band rather than from behind. All night I couldn't get a good tone. I tried all kinds of eq settings and running direct to the amp but it just sounded "hollow" for lack of a better term. I've never had my SBMM ray34 sound so bland. When adjusting bass and mids it was a losing battle. I've never experienced that before where it was like the tone was just being sucked out. Thoughts?
