    I must have edited out my question last time in. I better put it back.

    I have the svt4pro and two pr410hlf

    I don't seem to be getting the power I expected from this setup. The head claims 1600 watts. each cab says 1200 watts. but I am still having problems cutting through when jamming with the band. So I turn up, but this seems to lead to a lot of clipping especially down low on a (5th string) I am Tuned G D A D A. You can definately tell I am in the room but the clarity is not there. And I am not really even cranking the gain or master.

    I am playing a warwick infinity through this setup. Seems through all the cash, this setup should work somehow. what am i missing?

    How are you setting up the cabs? It should be 490 watts per side @ 4 ohms right? This should be plenty of power. The preamp section(gain,eq low/high boost) will effect the volume drastically. Also the -15db button will raise the volume considerably(should be pushed in).If you run too much bass, this could be the problem.Try boosting the lower/mids and cut the bass.

    The first thing I would do is try to set the EQ flatter, also check the battery in the bass. Does the clip light come on? If you have the bass knob dimes you could cause a lot of the trouble you are having. That is a workable rig, and should sound loud as hell and huge.

    I just plugged my m2000 into a 12in 16ohm moniter speaker and it rattled my mirror. You definatly should make sure your not too hot from the bass or in overdrive mode (lol). When in doubt read the instructions!

    I agree. Pretty much start with your EQ Flat & add/delete alittle as needed.

    How is your EQ set now?

    I now have the "ultra low" "ultra high" and "bright" switches out. the compression is all the way up.
    eq. 33hz @ 10
    ****80hz @ 2
    ***150hz @ -4
    **& 300hz thru 8khz at -12
    the eq level just a touch above 0
    frequency @ 2
    the mid & treble all the way down, bass about 3/4

    Thanks for all the help. Nino-Brown, XxBassmanxX,cjlbass, jawzzz.

    lesson #1. push all the buttons in and turn all the knobs up. right?

  7. I'm thinkin that youre just going to get mud, and no cut from those eq settings. Boost those mids! Boost boost boost!

    the power and the growl is there, and my speakers aren't hinting at clipping. Never had the gain and master up so high B4.
    I was just trying to compensate for the guitarists abundance of Treble. He uses more than anyone i have jam'd with.
    I will mess around with the mids a little

    ??IOW?? now I have to figure out the forum lingo.
    anybody have an instrucion manual for that???
  10. IOW means in other words

    If it were me, changing your settings...theoretically...

    eq. 33hz @ 1
    ****80hz @ 2
    ***150hz @ 4
    **& 300hz thru 8khz at 5
    the eq level just a touch above 0
    frequency @ 2
    Try the mid about1/2 the treble slightly above 2 and the bass slightly boosted here...

    This could sound good but then again, could sound worse...Just what I'd try first if I were testing out the SVT...


    P.S.When the guitarists I jammed with had way to much treble(like, if he hit a note, your ears burned) I asked them to turn the treble down a little, since it hurt my &^#$in ears!

    hey, did you replace basskahuna (Grandon) or are you guys jamming together?

    He's a member of these boards too.

    Thanks. IOW That helped. Not sure about those settings but they would allow me more cntrol on the Warwick.

    I guess those cabs are easier for you to lug around. If you still do the lugging. And that dude in nightwish has my exact bass but he only has 4.

    Yes I Am... the replacement.
    Grandon has a great sound, I will take suggestions from him any day. I would like to know what he is running.

    I have toyed with the head and bass all day and I think I have the answer. Never know til we are all jamming. I think most of the problems may have stemmed from my zoom fx pedal. it is not in the mix now.

    Next I have to figure out how too thicken the sound of my first three strings. Such a drastic change from the last two. Especially since I am Tuned G D A D A.

    Set the EQ flat. Everything flat. Lo and Hi boosts off. Start playing with the band. Adjust the EQ as needed to make yourself sound good in the mix. What sounds good when you're playing alone (scooped mids) translates to mud with a band.

    yeah the cabs say 4 ohms
    I took electronics a long time ago, so I am a little foggy on the math. All I know is the svt4pro says 1600 watts mono (bridge). And the cabs say they handle 600 watts rms /1200 watts program. So it seems I should be able to get more out of the system than 490 watts.

    I guess I could run them in-line out of mono. or what? suggestions?

    BTW what does 1200 watts programming mean?

    I have had the same exact problem that you have mentioned, I have the svt 4 and two bxt 4x10 4ohm cabs. It took quite a while to figure out how to dial it in, but over all I am disapointed whith the power output of the amp. You can barely use the eq on theese things without losing to much power.When I am running one cab I run it mono bridged for max head room and cab output. When I use both 4x10 cabs I run them stereo. If you bridge a cab be sure to change the configuration of your speakon cable, otherwise you are only getting one channel.Also you cannot run the cabs in mono unless they are both 8 oms ea, the head in mono cannot push a 2 ohm load ( two four ohm cabs) hope this helps.

    I run the same way. 1 cab mono/ 2 sterio. I don't run my eq much over 2 besides the power problem, it produces hiss.
    I am noticing that the SVT-410HE is an 8 ohm cab, that is what i should have in the first place, even though the watts drop 200. It seems like give and take. All Ampeg 15's are 8 ohms but also drop in watts. The BXT's give you a choice of 4 or 8 ohms both in 15 and 410.
    Thank you seansbrew, the math is coming back now.
    Want to buy another SVT4 and a couple o 410's?

    I am learning a lot but it's all leading me to my stash of valuum.

    I am curious as to how your rig sounds compared to mine. I live in the Denver area, maybe we could get together sometime and compare. Who knows, we could stumble on to a solution.:bassist:

    You said that the compression is all the way up... Try turning it all the way down. When the compression is turned too high the same exact thing as is happening to you will happen to my Mesa; no guts, empty sound, trouble cutting through the mix- Try with no compression and dial in to taste. Leave all other settings flat. Get your pre gain set first, then fiddle with all of the eq-ing.

    a QSC3002 and and Ampeg SVT-Pro should solve any such problem :)
