Using tissue and paper towels as mechanical EQ

I've had a pair of HD800s here, and I just can't really take the 6K spike. I know there are some mechanical mods.

So, anyway, the other day, I thought, "f**k it," and got a paper towel. Bounty in this case.

At first, I folded a piece twice, essentially making it 4-ply. It was too dead, and took off too much top—the place where the HD800 really gets it spacial definition.

Then I tore the pieces in half, and only folded over once—making 2-ply.

I'm at least to the point where I can enjoy the HD800s more.

I know this is a quicky solution, but it's a solution nonetheless.

I've engineered recordings for years, and sometimes you've gotta do something quick and dirty to get the results you're wanting. And a lot of those moves and tweaks are mechanical. Moving the mics, changing mic positioning, putting up absorbers, using wood sheets under percussion instruments, folded paper towels taped to drum heads to dampen, a piece of sponge near the bridge of a bass guitar...

And while I don't think this is a permanent solution, maybe something permanent isn't the solution. And on-the-fly tweaks offer a lot more versatility. This way, I have the ability to customize some of the brighter and hi-mid hot headphones, depending on the music and particular file quality and sound.

Anyway...anyone else out there playing with quick and dirty tweaks? Or have thoughts on any of this?
