    didnt see a post that went into enough detail for me

    how many watts would be going into each cab?

    Afaik there wouldnt be much headroom so im wondering if a higher wattage amp would be more beneficial, but the mb800 fits so well with those cabs (obviously).

    Also if anyone feels like giving me some info on the fet preamp i would appreciate it but im sure there threads on it

    Each cab is going to get roughly 400w. It does 800w at 4 ohms, so divide that in half.

    You don't think there wouldn't be much headroom? I think you'd be surprised at how loud it would be going into 8 10's. GK's are well known to have very honest power ratings, and they are loud.

    i was under the impression that headroom was watts above what your cab is rated for, and just not turning up too loud.

    Feel free to educate though!

    Headroom is basically the ability to continually turn up in volume and still have a clean sound. Low headroom would start to distort once you get past a certain point.

    Headroom is the usable available power/loudness above your average playing level. The harder you play or more you "turn up" the less available headroom you have.

    There is NOTHING wrong with having cabs rated for higher input power than your amp can output.

    so as far as the fet pre amp, afaik its a tube emulator type deal? Ive read that they can get pretty close but how warm does the tone get?

    Would i be missing out a whole lot not getting a hybrid amp?

    That only you can decide. I owned all tube amps for decades. Went to the JFET opamp 800RB, didn't miss the tubes, now I play a Fusion 550 and really enjoy how Mr. Gallien designed that 3 tube preamp. Same as is now used in the MB Fusion and sometime this year maybe, the MB Fusion 800.

    I played a 700RB II (FET front end) and it has good harmonic treatment. The tube snobs will tell you the amp HAS to have output tubes and also the output transformer to get "tube warmth". To their ears you may, mine I don't, you may or may not. ;)

    +1, I have yet to hear a fusion of any type, but the MB800 is very warm with a rough around the edges sound if ya want it. I may be wrong , but I think the MBE cabs have the same drivers as the neos without the bi amp capability, if thats the case , 2 mbe 4x10s will be crazy loud:DI would very much like to hear a mb800 fusion to compare, HINT NINT HINT MR G!:bassist:

    The 210,212 and 800 watt 410 are the same cone speakers as the NEO series. The horns are the same as the MB combos. Don't know about the 115MBE but I'm pretty sure the 400 watt 410MBE are ceramic speakers instead of NEOs.

    afaik your right about the mbe's not having neos.

    Thanks for all the input guys, lots of help as always. Now i have to decide if i want to save up for a used genz benz streamline 900 or just go used gk!

    My mistake, I thought they were the same, If you can find a used NEO cab get that I love my 2x12s

    You were partly correct! The 210MBE, 212MBE and 800 watt 410MBE are the same speakers as the NEO series (except the Horn). :)

    .I thought so, I think I saw RAG post that they were, It makes sense since the cabs are so light.

    OP: I think you should forget about cab power ratings entirely. They aren't really too important. And you certainly don't need to worry about what they are in comparison to your amp.

    Also: I had a 210 MBE. Didn't care for it. It seemed very bassy and not very loud. Got a Neo 212, that I like better.

    Hi.
    I play my MB800 through 2 Mesa Boogie powerhouse 410s. I don't think anyone would dispute that they are very capable 410 cabs. They are rated at 600 watts each, but I don't really pay much attention to the rating. the bottom line is they are capable of delivering a lot of volume. The MB800 gets them to their limits very quickly. I have several ampeg heads including an SVT2pro and SVT4pro. Both of these are loud heads that can also push the cabs to their operational limits.

    BUUUUUTTTT- the MB800 is a fraction of the weight. is a fractions of the price. gets louder faster. IMO sounds better. and is in most respects a technological light year ahead of my old lead sleds. Don't get me wrong- my 'pegs have their place in my stable. but the MB800 is the head that i've been waiting for for 20 years.

    You can't go wrong with it. especially if powering 2 410s is your goal.
    ymmv- but probably not by much.

    An MB800 into any pair of 4x10's would be a bone-crushing rig. A paint-peeling, soul-owning, guitard-belittling gigantic pile of balls-on-the-table awesome.

    It most certainly is. MB800 paired with twin 410MBEs. Lovin' mine!
