OT: Inexpensive monitoring...

The Mackie Big Knob is pretty nice, I used it for over a year. I now monitor through a HUI. They're just attenuator knobs. I set the above to unity and adjust my powered monitors to the proper SPLs

I never thought of adjusting the level on my KRK V8's because the control for it seems so inaccurate. This makes more sense though, b/c then I could crank the Big Knob all the way and know that I'm at the proper SPL for monitoring. Now I just have to borrow my buddies SPL meter to setup... Are there any other products similiar to the Big Knob that just act as attenuators?

This works great:

The NHT PVC (passive volume control) is a simple box with a very high quality stereo attenuator & balanced XLR/TRS ins and outs in a 1/3 rack space footprint. They work great for adjusting the level of your monitors without coloring the sound. They cost around $175 list.
