Any way to Mod my Volum control?

I bought a USB sound booster a while back and it works great, but the difference between 8 and 9 us big enough. If I try to turn the volume up a hair my pudgy fingers make it go up by 4-5 rather than just 1. So is there any mods that I can do to extend the length of the Volume bar? I will indicate how big I am looking for in the picture. Or better yet, is there a volume control mod that lets me type in the number, so instead of relying on my pudgy fingers to try and eyeball it I would just type the number in.

My OS is W7.

 

Hi

If you simply click on the Volume icon in the task bar so the picture you posted is showing, using the UP or DOWN arrow keys moves it one number at a time. I realize this isn't what you asked for, but it seems it would definitely help in your case.

 

You can also use the scroll wheel on your mouse .

 

Mcsmc that is what I will start using until I can find someone who knows how to mod this thing.

FED UP the scroll wheel moves more than one each time I scroll. Thanks for trying though.
