Can you give me an exemple of a song or a group that have the type of sound you want to have?
First, to have a clear, bright and large sound, you must take a condenser mic with an "omni" position. The closer the cell of the mic is from the mouse, the more intimate the sound will be. Generaly, put it 10-30 cm from the mouse, don't forget to put a filter between the mic and the mouse to avoid "pop" sound.
I found an image on google that show a correct position.
After that... you must treat your track: equalisation to make this track compatible with the rest of your music. Compression to ajust the level along your song, and compression to ajust the dynamic compared to the other tracks, and ambiant effect (reberb, delay) to give relief.
Do you have a file that we could listen to find what you did wrong?
