I've been struggling to record vocals on to cakewalk Guitar tracks for some time, I couldn't get enough volume by connecting the Mic straight in to Mic input and couldn't get enough volume from the Line out of a guitar amplifier, because the amp input is designed for a guitar.

Anyway i bought a new microphone today: it's a yoga EM-278 and requires a 1.5volt AA battery.
i found that the battery powered Mic connected straight into the mic input gives enough output to get a half volume recording providing I sing quite loud,
i copied the vocal track onto the track underneath and doubled the volume.
I can now continue my quest - to make a reasonable demo - the new Mic cost £20.
The output impedance of the Mic is 600 ohm
