GK mb200 ultra light head?

Status
Not open for further replies.
No problems, it will just pull less wattage than the 200 it is rated at with a 4 ohm cabinet. I think you will get about 140 watts out of it. I use an 8 ohm GK Neo 112-II cabinet and it sounds great.

Having said that, GK should have come out with some 4 ohm cabinets to pair with this head. Most people aren't pairing two cabinets to get down to 4 ohms. That defeats the portable nature of this head. I would have at least liked for them to offer their Neo cabs in 4 or 8 ohm options.

GK has come out with4 ohm cabs to match with the MB heads. The MBE212 and MBE410 are perfect for getting the most out of an MB200.
 
Anybody have any real world experience with the MB200 compared to the likes if micro heads from Genz Benz and Mark Bass?

I've compared mine to my EA Micro300 head. The two heads have different voicing. If I EQ the MB200 to match the voicing of the Micro300, then they sound basically the same. The Micro300 is more powerful than the MB200, but both are more powerful than what I typically need for a jazz gig.
 
I just paired my MB200 up with my Acoustic B115 cabinet with a Carvin (Celestion) 4 ohm PS-15 speaker installed. I've got my BBE sonic stomp in front of it and what a sound. The 4 ohm 15" gets the most out of it. I'm going to try it with two guitars running 22W / 30W and drums on friday. This head deff has the tone. Sounds better than my BX1500/BRX10.2 combo.
 
But how much more expensive was the Micro300?

I bought both on the TB classifieds. :hyper:

The Micro300 was $350 and the MB200 was $160. Or thereabouts. And I admit that both were impulse purchases. :rollno: I was perfectly happy with the Micro300, and I bought the MB200 to find out what all the hooplah was about.

If you eq the Micro300 to sound like the MB200, does it still go louder? I used to own a Micro300 as well. I can believe that it could sound louder, but I think it has a lot to do with the tone. I never found that it sounded as full and deep as the GK.

Well, since I spilled the beans in the other thread, now I have to stick to my own beliefs:

Power is power.
Loudness is loudness.

Power is not loudness.
Power plus effects plus signal is loudness.

Both the Micro300 and MB200 have built in limiters. I think that the Micro300 has a higher limiting point, but I don't remember the exact numbres. If the preamps are dialed to have the same response curves, then the one that is more powerful will indeed sound louder. How many dB louder? Not a lot.

"Full and deep" is probably due to the scooped voicing of the GK when its tone knobs are centered. I'm playing through a speaker that was designed to give me the tone I wanted with a flat amp, so I have no use for scooped voicing.

The second channel of the Micro300 is useful to me. Sometimes I let a guitar or keyboard plug into my rig when playing low volume gigs.

I've only read 22 pages of this thread, and maybe it's been asked in the latter pages, but do you need a pre-amp with the MB200 for use with an upright, say with a K&K Bass Max pickup? Or is OK just to plug into the amp and play??

Thanx..

I think you just plug in and play. At least I know tombowlus took this amp over to his friend's place, who's primarily an upright player, and they both loved the amp for it, and as far as I know, they didn't use any outboard preamps.

Well I'am very pleased withe the MB head ,I use the 1-15 light GK 8 ohm neo cab ,and works great,I think to my ears the neo 1-15 is tight for a 15 not flabby or boomy like some 15's I have tried. and @ 32lb it's a breeze to carry too.
The speaker efficiency has alot to do with loudness, so different cabs are going to sound louder than others.
I think we bass players should not be pushing our amps,get an amp with at least twice the power you "need",it is about headroom.
The MB200 was not designed for coliseum gigs, but for small gigs it 's a great amp ,and yes you can mic it or run it thru the board for larger gigs,,,
Now what the future holds,some day and it is comming, they will have an amp the size of a cell phone that you can wear on your belt that will be battery powerd and around 1000 watts rms @8ohms with programable EQ and effects....
It's on the drawing board ,just wait... LOL

The MB200 works very well with K&K pickups...even w/o a preamp. I even run my Martin acoustic guitar with K&K pickup through it. It sounds fantastic especially with the "contour" switch on.
