Way TOOOOOOOO Much Treble

[barryathome]

I bought one of the 75’Th anniversary models. And as each day goes by, it gets more and more trebly. I mean I almost have to put my presence and treble on zero, really zero, on all channels, all modes. When I first got it a few weeks ago, sounded great, now I can barley use it.

You'd think especially on these models they would be flawless. I spent 4k on this amp.

75th anniversary Mark V?

Am I missing something?

I think he means he got number 75 of the 40th anniversery models.

Have you called Mesa? I can understand the frustration, but if you haven't owned a boogie before, you'll get to see what first class customer service is. Marcus sat on the phone with me one day for 10 minutes while I swapped tubes on a second hand Mark IV that was 6 years out of warranty.

They will take care of you. I understand you frustration, but between shipping and tubes, there are things beyond there control that can happen. Just rest assured they will make it right!

When running front of house I'll notice cut to hear more of something else it may be "covering up" yadi yadi... this begs me to ask:

Have you lost low end?

1st. Yes I got number 10 of 75 of the 40th anniversay Mark V's. Its in Saple, and you can see pics on this site if you are interested.

2nd. I don't think its lack of bottom line, it can get pretty muddy.

Most importantly, it is slowly getting worse, ear piercing tone. It wasn't like that when I got if a few weeks ago. I've not played it in days due to the tone issues.

I"m at a loss right now.

 

[GIG4FUN]

well

I say it is Mesa's problem period. You shoudl not have to think of anything but calling them and getting a RMA. That sucks big.

I know when I switched the reverb wires accidentally on my Mark IV, the reverb turned into more treble. Just throwing that out there.

sorry to hear about your problem......

i had a similar problem a while ago, the amp became very trebly, harsh, the bass was unfocus and loose some output

try new powertubes and no change so a focus on the preamp tubes and my V7/driver/phase inverter was the problem

hope that helps

Definitely start swapping tubes. That's the first rule of tube amp troubleshooting!

If it's a new amp under warranty then it is Mesa's problem not yours!

I moved around the power tubes and it mad a difference. However, now on Channel 2 the Edge and Crunch volume are normal, switch to the Mark I and the volume goes way down, all 3 have he same settings. Any ideass on this? FWIW, the MarkI is the worst setting on the amp.

Just not sure what Jesus would think about that video??????

a more-than-small volume drop when switching from Edge or Crunch to Mk I, in my experience, is normal. with my settings, if i have the overall Master Vol on 9 o'clock when using the Crunch channel, i have to turn the master up to 10 o'clock to make Mk I sound the same loudness.

I think this is normal as well.

I have to disagree. Try this: turn the GEQ off and the bass EQ to 9:00 and then crank the presence to noon or more (to taste).

Tried it and you are right, this lesson has taught me, how much you need to tweak this amp, but what's amazing, is that you can shape it in so many ways, to me, like having 9 amazing amps in one box......

Really not sure I get your comment. I'm very happy I made the decision to buy the limited edition amp. Truly the most amazing amp I've ever played through, and just looking at it, well is stunning.

So yes, I felt the need to buy the special edition.

Ain't no shame in good taste! Hardwood Mark series combos are iconic.
