This has been helpful. I am coming from a recent history of in-ear-monitor with enough stage-monitor (lows) to vibrate my pants leg to make it "feel" real. I've played through an Ampeg 810/SVT3Pro combination and gotten a big smiley-eq tone, which seems to go well for smooth-jazz/slap funk but...
...for a standards jazz/R&B/blues "round sound" I'm shooting for something a little closer to dsanders' tones on his band link (yeah, I know it's produced--but that's closer to the sound I'm hoping for.) I want to avoid giving the G-string enough honking mids to stray into the guitar freqs. It needs enough lows to stay in the big fat round Bass family. (It's just the skinny kid in the Bass family. ..and a bright one at that!)
As the stage volume increases, I have heard the midrange (400-600Hz) start to take over the deep lows (on 410's) and I find myself adjusting more than I like.
It sounds like the DB's may bring the low-end up while keeping enough midrange throat to balance with the rest of the band. Does this rate with your (collective) experience?
What bass and head and strings will you be using?
