The Sennheiser e609 Silver may look like a very different microphone from the Shure SM57, but as the old adage goes, "you need to compare the frequency response charts of each mic and listen to them side by side in a controlled context." I believe that one was from Plutarch.

As you can hear, there are only very subtle differences between the two mics, though this may be the point: the smaller, side-address e609 can easily perch above rack toms and needs no stand when slung over a guitar amp, while delivering a tone any live tech will be familiar with.
