Oh the Mark III isn't going anywhere, was just looking to get input on which of the newer amps might cover more ground tonally, Mark IV, Mark V, or JP2C...the MIDI on the JP2C would be a thing of beauty for a complex rig.
I think the JP2C or of course the elusive IIC+ would be more in the III ballpark than the MkIV.
Here's an idea: The rackmount Quad Preamp has the basic MkIII circuitry, but with totally separate EQ knobs for the channels (2 rack spaces). Pair one of those with a Stereo 295 power amp or one of the newer Simul-Class 2:90s, and I have no doubt you could nail it. This is the best authentic MkIII solution other than running two MkIIIs at once, which wouldn't be very practical.
On the subject of Stryper, they've never received their due, but they hugely talented. It's amazing to me that they sound as good as ever (better really) on their latest album, even the vocals! For Michael to still be able to wail high notes at 50+ is inspiring. I'm guessing his much cleaner than average lifestyle for a rocker has helped preserve his voice. He's like the opposite of Axl Rose in that regard.
