active tone controls

[ruach1]

I'm looking for what is available in active tone controls for guitars. I know about the Fender Clapton mid-boost. Are their others? Especially, is there an active tone control which will pan from a "smile" eq on one side, to a "frown" eq on the other, and be straight in the middle?

Thanks,

Jay

EMG's SPC and EXG controls do exactly what you described.

These are two seperate controls. One to scoop mids and boost bass and highs, the other to boost mid and turn down highs and some lows?
