Made a clip of these excellent amps today. It's amazing to me how Ultraphonix like the GEM is. the SE88 really gets some of those Dumble type tones that I'd associate with recorded ODS tones (or at least my conception of them). I've never played an ODS. The SE88 has a pair of NOS winged C EL34s in it. I like them, but I think I prefer the original KT88s a bit more and I'll probably put those back soon.
