The best eq I've ever used is the one on old SVT's and V4's. They had a toggle for frequency center and a mid boost/cut. Why is the 5 position selector mid switch so prevalent? I'm only guessing it must be cheaper, but in practical application, I've never been happy with any one voicing of the five selections. I needs a bit more, ampeg! On the same tip -- I don't like the 5 modes on an Avalon U5, only the flat one. Actually, on that SAME tip, I don't really like parametric EQ's. I just absolutely DIG the old school Ampeg mid EQ. It's the perfect bass tool. With para eq's I feel there's too many options for crappy tones, and the 5 selector model is way too dumbed down. Mr. or Mrs. Ampeg, please grant my wish for the awesome old EQ, I'd really like to see it in something that doesn't weigh as much as the SVT-VR.
