Welp, my brand new Mark IV is fucked up.

[yngzaklynch]

I'd be on the phone with Mesa right away.

I would ship it to Mesa and have them look at it, I'm sure they would agree with you since you swapped in multiple sets of tubes....and the amp's brand new.

 

[MrDan666]

Damn.. that doesnt sound good Dave! Is there anyone locally who works on Mesa Boogie's near ya? I had a Mesa Boogie recommended tech who serviced my MKIII when it blew up, and it turned out a simple part had blown and needed replacing!

Where do you normally run 6600 on your Marks?

 

[PeteLaramee]

Oh man, that sucks. I hope this concludes as pain free as possible.

 

[Random Hero]

I haveto wait until Monday...since Mesa is closed.

Also, 3 of the preamp tubes were/are bad

Hey Random hero.... I usually use the classic V eq settings (or close to it).

Interesting that it was so bright. I think the Marks are bright anyway, especially compared to what I was used to, Rectifiers. Sorry to hear about the amp dude, hope it gets fixed up soon.

My brand new Mark IV screwed up the first day I had it. Its problem was that I lost all of my volume on channel 1 and had very little gain on my other channels due to a faulty LDR.

Does it sound like crackling paper almost? Cuz my Mark III does that and I replaced a tube, fixing it for a short while, but it has recently come back when I turn the volume up to a little past 2.

That sucks!!
Fortunately my new Mark IV worked fine out of the box.
I hope you get things worked out quickly.

No it sounds like static. It comes and goes intermitantly.

I have to mention though that this Mark IV sounds NOTHING like my MArk IVa

The B version i have now sounds different from the A version i had. I actually like the B version better. How bright is the amp if you pull the presence out? On my cabs the amp just sounds nasty with the presence pushed in.

Did you check/change the power tubes. This is the sound my mark IV made when it had a bad pair or 6L6's. You can try swapping the inner set of tubes and outer set and run it in 1/2 power (class A) and see if you get the same result.

I hope its something simple.....

Can you describe the difference? I have the A version and amp just curious. I have never done a head to head with the B version....

Mess around with the EQ more, I thought mine was bright too, but its easy to hide it. At first I didnt want to do anything but the "V" shape, but there's just too much not to leave alone in that amp.

I messed around with the EQ. Dont forget that I have a MArk IV already and I know how it works

Hey Dave, your Mark IV sounds a lot like a Mark IV i played at GC in East Brunswick. It was just a treblely windtunnel, i mean it sounded fucking aweful. I told the salesman that the amp was definity screwed up as my Mark IV sounded a lot better. But then the asshole asked why i was playing it if i already owned a Mark IV.

I notice a little bit more preamp gain and a little more of a bright tone from the A, not much, but i did notice it when i first plugged in. It's really not the sort of difference that would make me sell an A version just to get a B, but it's still a small difference.

Closed on Mondays.

Go back and read the first post....

Been a busy day, sorry. Guess you caught me speed reading instead of slowing down a bit.

Let us know how it works out and for some reason I see many used amps in your future

For some reason I thought you only owned III's. With all those bad ass cabs you need to organize a HOM again in a couple months, I regret not going to the last one
