One small correction. You can't say that the natural binding means a maple cap. Here is a first year (88) Alder CE24 with natural binding and no maple cap. In fact it is very much like Lifeson's except for his black headstock instead of my natural. I'd say his is probably 100% alder.
I think he might have 2 different red CE24s. The one with the piezo seems to have very little figuring on the top, while the other has more, though I suppose it could just be the light/photography:
That's the red one he played for most of the Counterparts and Test For Echo tours. Probably stock as well, and because it would have been acquired after 1991 I'm pretty sure it's got HFS/VB pickups in it.
On the Rio DVD he also played a Whale Blue CE24 tuned to F for The Big Money.
The pickups are the standard HFS/VB 's in that guitar. The only parts that have been changed on that guitar are the original winged tuners were switched out for the Phase II's at some point.
1992 CE24 Alder/Maple Top, Scarlet Red, HFS/VB, MilCom (almost as angry as the '90, great top on this one):
I love them...I love them all...
