    Say for instance I had a 250W bass head with a 2x10 and a 1x15 would that be loud enough to compete with a guitar player with a 100W head and a 2x18? Thanks

    unless you're playing death metal you should be ok. more power is always advantageous though.

    it depends upon style alot (and death metal isnt the only style whichis gonna need alot of power), and also what tone youre goin for. If you scoop your mids youre gonna need more power then if you boost em for example.

    i have a question though...what the hell is the guitarist doing with a 2x18?

    ...Been gigging for many years....

    ...and I say NO WAY Man !!!

    The guitarist's 100 watts will eat your 250 watts up!! (are you sure he's using 18's ??? that doesnt sound right....)

    My guitarist has a Mesa 60w tube combo(with 12" celestion)....that he runs with either a 2-12 or 4-12.

    I can barely keep up with my 900 watts, 6-10 cab !!
    (I do....but not without a fight !!!)

    Bass needs power !!!

    A guitar player with a 2x18? I've heard of 2x15s for guitar, but not 2x18s.

    You can reach the same levels that a guy with a 100W stack might be at with just 350W. The key is speaker cab selection.

    Obviously, you aren't going to be able to hold your own plugging that amp into a 1x12, but with any more than an 8x10, you'll be doing pretty good.

    If you're really having problems keeping up with your guitar player beyond that, then he's just playing too loud. If you're lucky, you'll be playing in front of an audience that paid a $20 cover charge, do you really want to pay them back with irreversible hearing damage?

    >>>>"A 900w amp that can't keep up with a 60w Boogie is rated using BSL (bull**** sound levels), IMO"<<<<

    Smash.....you are correct !!!
    ......The amp in question is the SWR Mo-Bass.....run bridged mono it's supposed to put out 900 watts into a 4 ohm load. The 6-10 in question is the SWR Goliath Sr.

    That 60w Boogie w/ 4-12 ext cab puts out 120 tube watts......it does scream !!

    While it is plenty loud.....I seriously doubt the Mo-Bass would spec out at 900 watts. (see the other similar post on 'Big Rigs')

    All the Bass manufacturers tend to exaggerate their true wattage figures .......some standardization is needed.

    good god! 900 watts barely keeping up with 100?! I have a peavey amp thats rated at 300watts at 4 ohms, i have an 8 ohm peavey 4x10 cabinet, i could throw my gutiarist and his 100watt tube guitar head & 4x12 cabinet out the garage door and across the street! i guess its the way peavey made the stuff.

    You know.....it's really not that unbelievable !!

    Given that wattage is NOT linear.....

    ...all things equal.....to double the perceived loudness......from 60 watts.....you would need 10 the wattage...or 600 watts !!
    ...now factor in speaker effeciencies.....
    ...and acoustics....and the factthat human hearing is much less sensitive to 'Bass' frequencies...

    and tone!

    if the guitarist has a real thick metal sound its alot harder to cut no matter what tone you have. if the guitarist has a really thin tone (ska), or even somehting along the lines of a normal rock tone than bass comes through just fine as long as its got a nice big hairy ass to it (ala the sunn 2x15 with traynor monoblock)

    and sorry for the visual:eek:

    i use the standard rule.....100watts guitar then 300watts bass...i use 450 watts from my peavey with 2 bottoms....and i have to just run about half volume and things work out just fine...my lead play uses a marshall with 2 bottoms:)
     
  12. There are no "standard rules". There are too many variables involved in this determination. Any band should work together to balance their sound. If the band members are competing to see who can be the loudest, then the music is lost.

    That said, the only way to know for sure is to try it.

    This is really going to depend on what type of sound you want. I have heard many bass players get over a loud guitar player with a 75 watt Peavey TKO. The sound was very bright and distorted. If you want a really full, punchy sound you are going to need a lot of headroom. This means the amp keeps extra power reserves to punch out the bottom-end when you need it. Wattage rating will not always tell you the full story about headroom either, but they are usually a good indication.

    If your guitar player is using 2-18's, it suggests to me that he or she wants to get a very deep sound. (Is he using a 7 string guitar?) If that is the case, you will need a lot more head-room to compete with him. You need to work out your sonic space with him.

    (I really hate guitar players who have no respect for others peoples sonic space.)

    So if I had a less low sound and more of a high and bright one, I wouldn't need as much power?
     
  16. That's correct.

    That's good in my case because the sound I use isn't a particularily low one but its not really really high... knowing this I hope this increases my chances of this amp having enough power.
     
  18. Our guitarists (x2) both have 100w amps and I have a Peavey TKO115 that will actually drown out the guitarists if needs be,

    Amen...
    Absolutely true !!!

    just make sure you've got a pair of SVTs handy to back up your agreements. Then once you've crushed everyone into submission, you can all agree to turn down. just kidding...

    It's all about coming together in support of the music you're playing. It's bigger than any of you. As long as it's my sound vs his sound, the music doesn't stand a chance.

    We had great results running stereo (1 guitar cab and 1 bass cab on each side of the drummer). It took us a while to get it dialed in, but once we did you could hear everything, from any point on stage.

    BTW, 2x18s ??? next stop, Bellvue.
