And in response to the original poster:
I've played through a couple of cabs equipped with oiginal 20W white untreated paper voice coil G12Ms. One was a '66 cab that I mentioned above, the other were two '66 Marshall PA cabs, belonging to forum member torger. Both shared tonal similarities - slightly brighter, more aggressive (but in a musical way), chewy and more open on top compared to my '69-70 cabs with G12Ms.
I've got a Hendrix reissue stack which I've upgraded with EC Collins pinstripe cloth, and improved the internal bracing to original specs (the new cabs don't have the same internal support, which does have a very noticeable effect). It's now equipped with Scumback M75-PVCs. I couldn't be happier with the sound of those speakers! While they will probably only sound better with even more break-in, they sound very, very close to how I remember those original 20-watters I've tried. While auditive memory is very fickle, I can compare them side by side with my later era ('69-70) greenbacks, and they compare very favourably, while having those white paper voice coil characteristics: more snarly, more detailed treble, but still smooth and musical. Superbly tight bass, much better in that respect than the later 25W G12Ms which can get a little muffly/muddy, but still warm, fat, swirly mids. They seem to have a slightly different mid peak...best I can describe it is they have more of an upper mid peak where the 25W ones have a low mid peak. They respond beautifully to a lot of volume...unfortunately I don't dare play a JTM45/100 at length into a 4x12 without attenuation, but they sound amazing when I do! *Very* Fresh Cream-like.
