I already own a couple of bullet mics. I'm thinking of getting an SM 58 or SM 57 for Christmas to be able to practice my acoustic playing. I will be plugging directly into one of my amps. (Zoo/BR-6/Super Champ XD) Will I need a DI box or something similar to match the impedance ? I am also wondering if Greg's ultimate 57 will fit on a mic stand and how well the 57 works for playing acoustically ? If it fits a mic stand that would allow it to be a dual purpose mic and I could use it for electric or acoustic right ? Any thoughts, experience, or suggestions would be appreciated. Santa is waiting to hear from me.

A DI might work. What's cheaper and easier though would be an inline impedance transformer. The Audix T50K is an old favorite among harp players.

DI boxes are usually for hi to low impedance (most commonly used for instruments to PA's).
You need an impedance transformer.
Something like this:

As Hawkeye says, the Audix T50K does the trick.

I use a 57 every time through pa, that is all you need, the rest is technique.
Just buy a standard 57 and buy a volume control from Gregg.
Wrap some rubber bands around the top of the mic to ease your grip, and good to go, Merry Xmas..

An Ultimate 57 doesn't fit a standard mic clip. It requires one with a larger diameter. They are available at music stores.

The Audix T-50 I tried was a tone sucker. A shame because I like the pigtail design. Of course, you can add a simple headphone extension cable to any IMT to get the same benefit. BlowsMeAway carries impedance matching transformers AND mic clips for Ultimate mics.

@Messy - the Ultimate 57 is one of the most versatile mics on the planet. You can mount it in a stand and use it for warm clean vocals or acoustic harp. You can hand hold it and cup it for a nice overdriven tone. If you have to mic an an amp it works well for that too.....
