Amps sounding bad/strange with volume high...

[jonl]

So I noticed this with two old marshalls into two different attenuators.
If I push the master volumes real high and hard the notes sound like they are farting out and spongey.
There also seems to be some type of octive sound as well.

This also occurred with my Diezel blueface with channel and master volumes when they get up around noon. This is both into two different attenuators and torpedo live.

I don't know how else to explain this, anyone else have this issue?

There comes a point when you crank the master on a vintage Marshall where it starts sounding worse, but not any louder. I think that's what you may be hearing. I think its too much power tube compression.

I agree with this

Even on a Diezel at half volume?

I guess I'll just post a clip of what I'm talking about

Once youg get past the sweet spot so to speak, with a master volume there comes a point of diminishing returns. The SLO even starts to compress a bit when you get waay up there on the master, but with a Marshall it's usually after 4-5 in my experience. Sometimes though, if the power tubes are getting worn out that change in tone can be very dramatic. I found that to be the case with the second 2C+ i had, the Mesa 430s sounded good but once I turned it up a bit it really sounded bad. I popped in a quad of Mesa 425s and problem solved.

Triple check your speaker cable and/or try different ones.

Attenuators effect tone. All of them. Amps sound horrible too loud, all of them. As said find the sweet apot on master colume.


Also research Fletcher Munson to rule out it effects.

I'm also running a Marshall 1959 plexi into a Rivera Rockcrusher.
I have the same thing happen to me.
in this amps case, louder isn't generally better.

I've dimed this amp from time to time, but I generally rule against doing this.
Just took in my amp in for repair because of 2 bad screen resistors.
I don't know if this has anything to do with diming it, but it definitely stresses the amp.
Tone didn't sound the same either after a while, it became spongy and muddy after while.
Even put in new tubes....same story.

Best option for me is to stack an OCD and Maxon OD while rolling off the volume.
