gallien krueger mb question

Discussion in 'Live Sound [BG]' started by Bassometer, Mar 21, 2013.


  1. I just bought a gallien kruger mb115. I really like the tone through the headphones, it is pretty much my ideal tone.

    I am ampless at band practice - a Zoom B3 into the board. I don't really like the tone of the Zoom. Our practice area is really small and we have agreed to be ampless.

    If I buy a GK200mb and run the DI into the board will I get a similar tone to the MB115 headphone tone?
     
  2. So long as it's the same preamp, which I believe it is, yes you should be getting the same tone coming out of the pre section. Now if you want it to sound exactly like what you're hearing in your headphones it may not sound identical. Your headphones may be coloring the sound to some degree unless they're studio monitor headphones made to not color the sound at all. Also, there may be some eqing going on at the board that you don't hear when just going through the headphone out and the room will have some effect on the sound coming out, since you've got quite a bit more space acoustically from speaker to ear that can cause a few different sound things to happen.

    You might try checking out the thread over in the amp or effects section on using the B3 as a preamp because there are quite a few internal parameters that you may be overlooking that are causing you to get less than ideal results. I love they way my B3 sounds and I use it through the power amp of my PF500 as my pre. I think it's a top notch preamp, especially going straight to the board.

    The B3 only falls short in that there's no way to initialize your patch quickly. You should make sure that in the total menu your patch is mixed 100% so you're not getting a bunch of raw bass, set the level on the page 100, go to the global menu and set the volume to about 60 and then on the amp sim set the level to 100 and scroll over to page 3 of your amp sim and see what the cab simulator mix is. Most amp sims on it are preset at 50%, which might sound good, but in my experience usually doesn't. If you want raw preamp sound coming through the system, set it to 0% mix, and if you want a mic'd cab sound, put it at %100, and then you can even scroll through the cab models to see if one suits you better than the original one assigned to it. By taking these steps when setting up your patch, you can be sure you're getting a healthy signal to the board. Also be sure that the pre/post switch isn't engaged so that you're not accidentally bypassing the amp sim all together.

    I don't write this post to be insulting of course, merely because I realize not everyone is glued to the manual on something like I am and I don't believe that in order to get the best performance from your B3 you can just plug it in and twist a few knobs. Also, I think you may be trying to fix a problem by throwing more money into it, when it may be as simple as developing a better understanding of equipment you already have. If you've already written off the B3, that's fine. But, I think if you work with it a little, you might just find that you can get what it is that you're looking for.

    The answer to the original question is no, the DI won't sound the same as the headphone out. Look at the block diagram in the user manual and the reason why will become obvious.
     
  4. wshines1892. I appreciate the advice, this gives me a good starting point. You are probably right, the B3 is a good pre-amp, I am just not the "tweeking" type. I normally run flat (or slighly boost the bass if I am runing the brigde pick-up only). I should dig deeper into the B3.

    There are some good tones in the B3 but most of them are novel to me like the 70's porn sounds. I don't use effects, I bought it for the modeling capability. I am going to take your advise and sit down and spend some time with it. If I can get a good GK or Mark Bass tone out of it I will be happy.

    Thanks

    Personally I would bypass the B3 altogether and run my bass direct, especially for rehearsal purposes. If your bass doesn't sound good by itself then find one that does. ;)

    That's just my personal philosophy; YMMV.
     
  6. +1 ^^^ This.

    PS: OP, if don’t mind dragging your GK MB115 to rehearsals, you could plug the GK MB115 headphone output into the mixer.

    A couple of things...
    1. Use the mb200's line out to the board, not the DI. If you are 20 feet away, it won't matter
    2. The B3 takes some time... The good stuff is therebut you have to do it... Thefacotry settings are too generic to be useful.
