well here's my TOWER of FU*KKING death
my thoughts are exactly as everyone has represented herein.
Channel 2 fu*king ROXX. It's everything the original 100W was not - brigher, more hi-mids, more gain, with still the "openess" that the original 100W was known for. Of course you can't increase the gain without being a "bit" more compressed

but man do those pinch harmonics JUMP outta the cabinet.
as has been noted the overall gain of Ch2 and 3 of the 100S is higher - but IMHO the Ch1 (green) also breaks up a bit quicker than the original.
I'll have to experiment more, as I'm playing a Anderson DT7 and the H1- (even split) tends to be HOT.
Anyway, pix or it didn't happen!
