Why is my bass cab making a distorted muddy noise?

    I have a USED Hartley 4x10 8ohm 400 watt cab with a behinger 300 watt 4ohm head I played a live show recently and in order to be loud enough with the drummer and gutairist (gutairist has 4x12 marshall half stack) I have to turn the head to full max and when I do that the cab sounds very distorted muddy not very pleasent or clean at all and when I turn it down to where it doesn't make that noise it's too quite. I just want to know either the problem is with my cab and the speakers or something with the head?

    How do you have your eq set?

    My first thought is one or more of your components has reached its limit.

    You're asking too much from your rig. If you're turning up to full max, you need more power and/or speakers.

  4. Either the cab is distorting or your amp.

    Likely the cab. See the other "amp or cab upgrade" thread.
     
  5. Oh, snap, OP is the same!

    4ohm head

    Is there a 4 ohm output on the head and is that the one you used ?

    300 watt at 4 ohm head = 150 watts at 8 ohms. Behringer watts subtract another 30%= about 100 watts. I'm guessing you are clipping the snot out of that amp.

    ^ when you are pushing components past their comfortable limit, they start chopping the tops off waveforms ('clipping'). No audio components are designed to run at '10'. Clipping is a really ugly 'farting' sound. You should be running you amp at about 30% when going full out. Something in the 500 watts at 8 ohm area.

    Is it either of these? I've had them on the bench, and they produce about 80 watts, and 90 watts at 8ohms. Surpisingly, the old 3000T was the better sounding amp, and good for what it did. On both, lay off the ultrabass setting, it gobbles power.

    Yes mines the 3000 and ohhh ok I know that it's not good to push amps at full10 but when I don't it's way to quiet agaisnt my gutsisist and drummer so would you recommend getting a new amp potentially around 500 watts 4ohm

    500 or so watt class D amps are so affordable now I would highly recommend it. Shopping used will get you a deal since these amps usually work, or they don't, so it's pretty easy. I picked up my back-up amp, a Peavey minimax, which does 350 at 8 ohms for a hundred bucks.

    I'm looking at this used very good condition fender rumble 500 it does 350 watts at 8 ohms do you think this will be enough to get loud enough volume for live shwoe without clipping?
     
  15. So dividing by ten is still out by a factor of 3 now? And folks cry about other folks ragging on B'ringers.

    If the rumble 500 head can't keep up with your band then you need a new drummer and guitar player, not a new head.

    The rumble is great by the way.

    The rumble 500 is a good amp. That said your 410 will never ever be able to keep up with a Marshal 412 no matter how much wattage you throw at it. Either add an identical 410 and get the rumble or get the rumble sell your current rig & get an 810. Regardless invest in good hearing protection BEFORE your band mates destroy your hearing.

    Good luck

    Aha!! The dreaded Flying geese EQ setting.. here is what you do, turn Shape to 0, then set those sliders to flat. then boost the 160hz. Roll of the treble on your bass to taste. It’s going to sound like crap by itself, but when you start with the band, you set really well in the mix.

    The problem is with the EQ on the the amp is you are removing the sounds you need to hear.

    Perhaps stop dropping it in or dragging it thru the mud?
