    Lately I've been having a really hard time dialing in my RBI. I'm running the RBI and a QSC Power Light 1.8 through a Bag End Q10BX-D. My problem is coming mainly through the PA though. The only way I can describe the tone is Boomy. When I play about G# to B on my E string I get super loud tones through the mains. All my other tones are absent. I use a Peavey Cirrus bass with Elixir strings. Usually I EQ my Cirrus Bass-8/10 Mid-5/10 Treble-7/10.

    If anyone has any tips or ideas to suggest I'm completely open to trying anything right now.

    One more thing, I have a dbx 160a on the way, would this solve some problems??

    bump because i'm starting to feel stupid..
  3. RBI and QSC PLX1602..... can be tough to dial in.....really the room has a lot to do with it. Don't run your power amp or PA gain too high, but drive the preamp a littel more, and back off the bass, emphasize the mids a little more and back off treble and pres. to suit your style.

    roll off your highs on the bass to, especially if that is active (isn't that a 18V active unit?)

    try it.......I am going thorugh an AMpeg cab (sometimes) and in small rooms, it never can get trottled enough to develop a decent tone. using a smaller cab lets it unfold more.

    Or at least that is what I found. SOme people argue about it. I burned up two really nice speakers learning to use my rig, and now, I understand it much better. I really back off on the power amp gain and try to drive the system more from the front, and add power as needed.
  4. If you get a chance - post a pic of how you are setting it all up. I will try to do the same this weekend.

    Seems to me that the problem isn't your stage rig, it's what you hear through the PA. If that is the case, I would investigate the PA.
  6. Maybe - but a lot of times, stage volume is the culprit.

    Another thought is what are you putting out to the PA>?

    If you are putting out dry signal, it is the mix at the board more than likely. If you are doing the mix from the Pre - you have control with the XLR controller on the front.

    Fuzzbass - you have a good point - I wasn't thinking about that.

    My stage volume is pretty low, we're using Aviom so the only reason I have a cab on stage is to feel a little rumble. Do you guys think that I should keep using the Sansamp XLR output, juice the xlr output, back off the power amp gain and raise the volume of the RBI? This sounds like a really good place to start...

    Something else that is sounding pretty good is to just go Uneffected XLR out, but that puts everything in my sound dudes hands and I lose my beloved tone..

    I'm so torn!!
  8. I go out unaffected and let him do his thing. A lot of your tone is your cabinet (My opinion). Get good sound and volume on the stage, and let him do his thing. You will be better off in the long run. (again - my opinion)

    people argue about this......
    It is - what it is.

    You sould always mic your cab to maintin the integrity of "your sound".

    Don't settle for less than you want on stage affects your playing.

    I had the same problem. I had to back off the blend knob a little. I was losing a lot of definition going full blend. Hope this helps.

    Great point. A tone that works through your bass cabs might not work through the PA -- not even if you're using nice cabs like Bag End.

    If you really want the SansAmp tube emulation to come through the PA, then work with your soundman: tweak your settings until you get good tone thru the PA (rolling back the Blend control as Badb suggested is worth a try). But keep the caveat above in mind: that is, you might have trouble getting good tone through the PA and your rig simultaneously.
