Like the topic says.
I have a Old Marshall Jcm2000 DSL 50 (that has only one volume knob). Its a good head but its very loud and it seems like the gain cannot keep up with the volume. It breaks up after the volume hits "1". Even if gain is maxed out. Will a attenuator or Master volume mod allow for more gain at higher volumes?
I would like a very tight "liquid" feeling with the gain rather than the crunch feeling it gives now.

Wait...you've got the gain cranked and you're surprised that it's breaking up? Am I reading that right?

So, you have a gain control all the way up, and at one you're saying it's got break-up (distortion).

Yes?

No?

I don't get it.

I think you need a new amp. What I understand from your post is that the distortion doesn't sound the way you would like it to sound.

Attenuator will allow you to get power amp distortion at lower volumes, not higher because at higher volumes you automatically get power amp distortion.

If you need more distortion, buy an OD pedal and boost your amp.

But I think the fault is in your amp - the distortion sound isn't what you are looking for.

I don't know if I understood your post though.

I, like everyone else here, is pretty confused by what you are actually wanting. More gain at higher volumes? Yes you will get that. Less gain at high volumes? Turn your gain down. More pre-amp gain at lower volumes? You are already achieving that. More power-amp gain at lower volumes? Buy an attenuator.

He's saying he's got his gain maxed out but isn't getting enough gain at low volumes. He has to put his volume past 1 to get the level of break up he desires (power amp breakup I'm guessing) but its too loud to play with. So he wonders if a master volume or attenuator will solve his problem to get the power amp breakup with low volumes.

I would like a very tight "liquid" feeling with the gain rather than the crunch feeling it gives now.

I have a JCM2000 DSL100 (same thing more watts) and it is easy to get pretty heavy distortion from it.

Are you using the classic channel or the ultra channel? I play in a Punk/Hardcore band and a Prog-metal band my DSL has no problem producing enough gain.

I use the ultra channel with the button out and only have my gain knob at 6.5. I do use a Bad Monkey and a GFS Greenie for boost to get a little extra gain, but is is not over the top by any means. This really helps get that "liquid" tone you are describing.

So what style of music do you play?
What are your settings on the entire amp?
What switches are being used (deep/mid shift)?
What channel and mode are you using on the amp?
What speakers/cab are you using?

Answer these questions and I can help you much better.
