One slider to control the total bass output

[Sam29]

So I can easily adjust all the bass without fiddling with multiple EQ sliders

Thought I explain a little more on why this feature is worthy. First, to understand what I'm talking about with my request, google image search "Rocket Player Equalizer" and you will see the bass slider it has.

I use the EQ 32, 64 and 125 to adjust the shape of the bass, but sadly my new speakers don't have an external volume control for the bass level. So having an slider to adjust bass level like Rocket Player does would be handy.

If anyone knows of a MB plugin or a 3rd party app that can do this, please let me know.
