I haven't seen the extrnal gooseneck thing for the Rare Earth. How is it hooked up?

As far as having to stand still, I have to stand kinda still anyway for the vocal mic ... and I usually only use the instrument mic for 'flavor' - and a boost when I play a solo, so I feel free to wander a bit, probably drives the sound man crazy, but it works for me!

I must say though, the Rare Earth (sans mic) really did surprise me with its qualities. It has a touch of the warm electric sound you would expect from a magnetic pick-up, but it has a clean string signal and it produces some very fine, true acoustic qualities too. My first impression was that 'yes it sounds like a pick-up' but 'wow, what a pretty sound!' I really have been very happy with it. I would definately consider using it in another guitar.
