Got my GK MB Fusion today!!!!

How do you like that 410mbe. I have one showing up soon, but didn't get to try it first. Not sure what to expect.
I really like mine but the gig will be the real test. It is pretty punchy with a 'tight' low end (in a good way). Plenty of mids and highs, especially with the MB-Fusion head! I think it will be great out in the real world...I never had much luck with real 'bottomy' cabs (Epi?).

We'll see...:hiding:
 
+1 Brighter, more aggressive in the upper mids, more sizzly up top (finally got to try one of these out briefly... quite similar to the MB500 to my ear, with a bit more character and complexity). The Streamliner sounds much more like an all tube amp. Not really scooped, just fat and smooth and big and warm and creamy, with a very accurate 'all tube' top end (almost a bit spooky).

I describe the Streamliner as a great micro choice for those who dig the SA200, the DB750 or the Mpulse600. The Fusion is much more similar to the Mesa M6 and M9.... more solid state than classic tube sounding, big down low, super bright up top, with more of a 'touch of tube pre' versus the all out 'all tube' emulation that the Streamliner goes for. I personally prefer the 'drive' tone of the MB500 for a more gritty tone than the pushed tube tone of the MBFusion, but that is pure personal taste there. Both seem to be relatively similar to me when run clean, versus the total night and day difference between the Shuttle and Streamliner in the Genz line-up.

Just like many all tube amps, and the DB750 and Mpluse600, cab pairing is a bit more key for the Streamliner due to that 'all tube' low end vibe. The MBfusion is much more solid state, with a nice 'tube flavor', and would seem to work pretty well with most cabs, like the F1 or Shuttle or whatever.

All impressive heads. To the poster with the LMII, putting a Sansamp VT pedal in front of that will get you into the MBfusion tonal universe IMO i.e., brighter and grindier, if you don't want to do a full head swap.


Thank you for this. Wanted to get an Aggie TH500, but the Euro price is astronomical. Took the plunge on this head instead. I can't wait to hear it myself.
 
MB Fusion 800 anyone? :hiding:


I would be all over this!
At Low levels the MB-F Gets amazingly close to my SVT-CL,
VERY Close ( to "my" sound that is ) and cuz of that i've got my SVT up for sale-- cuz i'm so happy with the MB-F ,
Sonic differences between the two are that the MB-F has a bit more High mids that i just can't get out without losing myself in a mix,
Also the tone thins out a bit when Turn the volume up on the MB-F , its gets more agressive = which is Nice, but i lose a bit of the tubey- creamy-ness , compared to the SVT which stays strong in that area of course,

So with that said i would hope a MBF 800 would solve that problem!
 
OK, so...three jazz trio gigs, and one full size rock gig later, I can say, this is a very competent little rig.
It's got nice, wide range frequency response. Plenty big lows, plenty high highs, nice snarly midrange inbetween.
The eq, while I ran it pretty much flat, also has plenty of flex.

And, plenty of power. For the jazz gigs, I used just one of the two Neo 112's, and had both the input and master gains at about 10 oclock.

For The Big Rock Show I stacked both 112's vertically, and turned up the input gain to about noon, dialed back some bass, and let it rip. With my Sadowsky RV5, I set everything flat. With my Fender Precision AE hotrod (loaded with G&L MFD P-pup) I snapped on the presence switch to give the P bass a little more snap.

That's it. Great tone. Massive headroom. Easy load in and load out.
Gotta love it.

Cool! Was hoping the 112s were good standalones as well.
 
Update:
just going by living room results, I see no reason why this won't work nicely for double bass.
King>K&K preamp set flat>one Neo112.

I think I kike channel one better with DB.
To get it loud-ish, without feedback, and sounding pretty dang good settings were:
input gain at noon, contour at about 9 oclock
all eq's at 11 oclock
master at 10 oclock.

low mid and bass seem to be good "anti-feedback" points, and a little contour helped with that too.

Not sure when I'll get a chance to gig it, since it seems my thursday night jazz trio thing has run it's course for now:( I'll report back when I do though.
 
so far, yes.
i don't have a wide range of cabs.
aside from the neo112's i got with this head, i'm down to
epi ul410
LDS 4x8, and LDS 2x8

Just kind of curious here, Chef, and maybe you have answered this in a previous thread, but, have you ever tried the Gk 700RBII ? The tone you are describing with this head sounds like the tone I get with my 700RBII, into a 215 cab with horn.
 
No sir. GK newbie, for the most part.
I've had GK supplied as back line for a couple things I did over the years, but I've never owned it. Pretty sure the supplied stuff was 400RB in both cases, but, my memory ain't what it never used to be.
 
While it might sound good with a fearful 15/6/1, I don't think it has the watts to drive that thing to full performance of that cab.

It's brighter and more responsive, and more flexible in terms of eq than the F1 I had.
 
im curious if this can drive a fearful 15/6/1 and also how it compares to a markbass f1/f500

I've had pretty good luck with the F1/f500 and the 15/6 cabs. Of course, they can take more power, and if you play very loud, you might appreciate more power. However, the GK micro and F1/F500 should work nicely for most with the 15/6 and 12/6 cabs.

The F1/F500 is more even, less low end and treble extended versus the very big and sizzly sounding MB line of amps. Max volume seems about the same, but it is hard to tell, since the GK master kind of goes from 'off to scream', so is louder at the same knob settings.

I prefer the more organic, punchy, 'natural' voicing of the F1/F500 myself (plenty of brightness, but much 'warmer' through its frequency range), but that super goosed low end and high end and upper mid/treble bite of the MB amps is cool also... just depends what you want.

The F500 EQ is a bit more powerful, but the EQ on the MB amps is more than adequate for most and pretty similar to the F1. Two very nice flavors of 'very good' IMO, but different enough that most would have a strong preference for one or the other.
