If you're using a lot of different guitars, amps and cabs it's a very useful mic. Sometimes a 57 just won't work and the E609 will. If you deal with the same setup all the time, it's not very necessary, but it's fun. Great on toms, works well on all sizes. Not the best for snare, it hangs too far over the drum. Sometimes it's pretty cool on vocals. It's a pretty versatile mic.
