MB-fusion reliability?

Currently using MB800 with zero issues and had a MB500 (also with no issues) before. Early MB2-500 models (couple of yrs back) DID have issues though.

 

Strange,
Sounds like ha was intent on selling you something else, perhaps something he did have in stock?
If you read the Mb Fusion mega-thread I believe there are almost no mentions of problems.
I do know the original MB500 had a LOT of issues!

 

I bought mine used here on TB 6 months ago. I've used it for probably 40 gigs or so with zero issues. The only downside is my MB500 is collecting dust.

 

100 or so gigs in and mine remains 100% trouble-free. It's a great little head.

 

Mine was trouble free until I lost it in a fire on christmas eve. I miss that head.

 

I've gigged my MBFusion relentlessly for 18-ish months or so.
So has Vic.

Only issue I had was the mute button got sticky; I returned it, they replaced it and shipped it promptly back. This was an issue with some early units, and soldering the switches a bit too hot.

I've had no issues since.

I'm going to be an early adopter of the MBFusion800 when it's ready.

 

I've had one for a bit less than a year, loads of band practice use, but only about 6 gigs. No problems at all with it.

 

I have never tried a Fusion.
What does the mutton button do?

 

My Fusion 500 has always performed great for me over the last year I've had it. The only issues I have with it is the mute button doesn't fully click in to mute, and when the fan kicks in, it is so loud. You won't be able to hear it during a loud show, but for quiet performances, it's very noticiable.

 

GAS'ing for that amp!

They need to figure out a new name for it though...

 

why a new name?

 

Actually I think they should rename the old one, because it's a series of MB Fusions now!
MB Fusion 500
MB Fusion 800
(MB Fusion 1100 will be the next I think, if you look at the power ratings between the MBs).

 

You don't think the G-K Grover has a nice ring to it?

I'd prefer they kept the model names/numbers simple (I'm a simple-minded kind of guy).

Fusion 550, MB Fusion, MB Fusion 800, ConFusion 2k, ... whatever...

 

+1 Same here! Gigs, rehearsals this little monster just rocks! My Mesa gets jealous these times

 

I propose Confusion 800

 

Im looking to get an MB fusion 500.
My main attraction is the tubes and the fact I can fit it in a single rack slot. (Apparently im the only person who still loves rack gear)
I would love to go from a 6u rack to a 4u rack road case with this little head and not have any unused rack spaces, but my initial thought is poor ventilation=heat=bad.

Anybody think this a for sure no-no or will the inhouse fan protect it enough?
Common sense tells me to leave room but it would just fit perfect with my setup.

 

One problem might be that in a tight rack you won't be able to reach the switches on top of the head. The head gets quite warm all around, not hot exactly though.

 

I wonder if maybe those Fusions that were returned simply got a run of bad tubes installed in them at build time. No idea what brand tube those Fusions are using. Or maybe the crate the finished heads were traveling in took a tumble and the tubes' guts got scrambled. Maybe the dealer didn't want to pop the covers & troubleshoot. (Not doing so was the correct decision -- both long-term and logistically.)
