Just got my MB800!
 

Thoughts... what a difference in balls compared to my MB500. I run two Hydrive 4x10 cabs and the 800 really packs a wallop. Dont get me wrong, the 500 is still a beast, but the added punch is amazing. Gotta go, more later...

Go warm it up and loosen some walls! :D

That thing's a hammer isn't it?!

A death hammer!

Love mine.

Got a hell of a deal on it too. I found a demo for under $500.

200 - 500 - 800
 

I just got my first "real" amp - GK MB200.

Hopefully I can work my way up to the MB800 eventually when I grow up...as a bassist, that is. ;)

Congrats can you make the head slide off of one of the cabs? :)

I have had all 3 GK MBs and IMO the mb800 is definitely the best. Features, tone, vol - definitely the best.

Handing over my MB500 today, Im gonna miss her....

SO?
 

...the MB heads have different tonal features based on thier built in EQ's, etc?

A TBer just told me he preferred his MB2-500 better than the MB500 based on its' EQ points. Just wondering. Been looking for a MB500 or MB2-500; not sure which now.

But that MB800 sure seems like it'd be fun. :bassist:

All three amps have the same eq frequency points. The mb200 has no mute and is missing the contour knob and instead has a contour on/off switch. There should be no difference between the MB500 or MB2-500. If it were me I'd go with the mb500 as its the last revision and seems quite solid.

I've been thinking about getting one of these next! I'm stuck in between an MB800 or one of the RB heads. Between the two which would you guys choose? I'm planning on pairing it with either a 410mbe or a 410 neo

I had RB's the MB's kick their ass... Im pushin two 1000 watt Hydrive 4x10's.

Don't sleep on those old RB's...they have some magic in their tone for sure. The cool thing is now that I'm using a high pass filter and rolling off some lows (around 80 Hz) I can get my MB800 to sound remarkably close to my old 800RB's. Remarkably.

The earlier MB2-500's had different EQ points, especially on the bass side. The later ones are identical to the MB500 with the exception of the switchable limiter.

The interesting thing is Bob Gallien looks in here on TB and the EQ points were changed due to feedback found from TB'ers.

Dang really? I always thought the RB's were like GK's top of the line lol

When I say that its for several reasons, and its only my opinion. 800rb, my killer rig from the 80's when I used to bi-amp. The unstoppable 400rb full frequency head driving hartke 4x10's. All awesome rigs. I bought a 700rb and kept it for two days before I returned it. It just didnt sound like I remembered GK's sounding. Then while test driving an 800rb Perry at Bass Central here in Orlando mentioned the MB series. After ten minutes I was out the door with an MB500. It just sounded better out of the box than the other GK offerings.

Stugotz - how do you like the MB800 with the Hydrives? Have you tried it with only one HyDrive 4x10? I'm thinking of getting a HyDrive 4x10 and an MB800 over their LH1000. I'd love your opinion, thank you in advance!
