I figured I'd throw this question out to the hive... I'm sure it's been covered before, and yes... tell me to search the archives... etc.... I'm using a Pz-Pre to double on my gig, and while it has all the features I need, notably Phase Invert, HPF, Variable Notch, Impedance Switchable Inputs, Sweepable Mids, DIs, etc... I keep thinking there must be something better out there. The Radial is okay...I've had issues with the input jacks, but it gets heavy use... I won't blame that totally on the piece. One main drawback is not having separate eq for each channel. I've checked out the specs on the Felix, looks great... but you have to choose between Notch or HPF on each channel... I need both. I also can't find a phase reverse switch. Any favorites out there?
