evolving_machine,
I think the Modern Vintages are great heads. I use them on one of my snares all the time. They are an older school type of sound with less attack and more warmth (just like Evans J1's, Fiberskyns, etc). Very nice for brush work.
They came with what I think of as cheap heads (Remo Ambassador top and bottom).
Although I lean a bit more towards Evans and Aquarians,
true Remo Ambassadors are good heads, IMO.
However I'm wondering if you meant
stock Remo heads? Remo makes stock heads for thousands of drum kits. The difference being that these are second level quality heads. Stock heads never sound as good as fresh, off the shelf heads because they were manufactured for a lower price point. That's to help manufacturers be competitive. These appear on just about every drum that's made by the big boys (Pearl, Tama, Yamaha, Gretsch, etc) with few exceptions.
Case in point: I bought my top of the line Yamaha MCAN drums in 2004 brand new. These were the absolute best drums you could get from Yamaha at that time. They came with maybe some of the better stock heads Remo makes called 'UT' heads. I immediately replaced them with Aquarian Texture coated/Classic Clear/Superkick heads and never looked back. I sold the unplayed heads on eBay.
I knew the heads, even better stock heads wouldn't sound the way I wanted them to. After throwing out that much dough, another $150 to make them sound at the top of their game seemed the right thing to do.
Hope this didn't fall away from topic too far.
Let us know how those Aquarians sound.
BTW: Don't forget to change out the resonant heads as well at one point for the best quality sound.
HTH
