the diver sounds a bit less hot, but way more full bodied, darker and more fluid
sounds really big, specially for leads
it has a thicker and more open midrange
I can't tell myself which one I prefer
for alder, I'd probably go with the diver, but I'm thinking I started to like the cold sweat better in mahogany
they have a very close output level, but they are very different from each other
the diver sounds really "alnico" (warm, fat, smooth, fluid, clear, open), while the cold sweat sounds very "ceramic" (tight, hot, sharp, bright, crunchy, aggressive)
