Got my GK MB Fusion today!!!!

The only downside I see so far is this:
the input pad ''pads too much,'' sucking the life out of things.
with a hot bass, I get better results dialing down input gain a tad, compared to using the active pad.

I find this to be true with most heads, but YMMV.
 
Gig one:
jazz trio, which turned out to be a foursome...piano, bass, sax, flute.

The MB-F and one 112 was waaaaaay more than I needed.
Tone was killin' with my Reverend BH5, which I ran in single coil with bias set a little towards the bridge pup, and tone rolled back a tad.
Channel B on the amp, input gain at 10 oclock, master at about 9 oclock, everything flat.

Now that you've gigged it, do you feel it displays any of that "tube amp" feel that's part of the Walkabout's thing, and so touted lately in Streamliner posts? ...or maybe you want to wait to turn it up a little more before sayin'...
 
I am really thinking of getting a MB-Fusion or a Genz Benz Streamline 600. I have had 3 GK Heads in my past and always liked the sound.

My MarkBass LMIII is just anoying me!!!Can't get the tone I am after.

I have a gig tomorrow night at a club and hall type gig at Providence College next Friday...This may be the final test after having the LMIII for 2 yrs.

Does the GK MBF get a creamy tone like the GB Streamline; or is it all trebly and clear-crisp?
 
You guys would not believe how hard is to take a good digital picture of the MB-F due to those horrible highlighted buttons ;)

It took good while to manage this picture, and it is still far from being perfect... (To photographing bassists: The red buttons are brighter by 7EV than the entire scene, and the blue ring is darker than the red buttons... And the red buttons are in reality bright white lights passing the red buttons...)

No.
There's really none of that to speak of.
Very different from Walkabout, and Streamliner.

For what it's worth, I love the Walkabout, and didn't care for the Streamliner and flipped it after one gig.

I don't see the MB-F leaving, but, I'll wait til after tomorrow to speak to that.

Yes, and, yes.
They're not even in the same sonic universe mate.

I found the SL way too soft and scooped for me. I mean, with someone else playing my bass, and me out in the audience, I couldn't even tell my ash/maple Sadowsky with fresh steels on it was strung with rounds.
The MB-F is much more mid-present and aggressive, and very much more to my liking; so far.
Jazz trio ain't much of a test.

Let me try an analogy:
Before the MB-F, if someone said they were gonna take my M9 away from me, I'da Chuck Norris Roundhouse kicked 'em.
Now, with the MB-F if you said the same thing, I'd only Jackie Chan punch 'em.
 
Chef, can you give us a quick rundown of the Fusion compared to the Streamliner?
Is it more aggressive, less tubby, less scooped?

+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.
