multi equalizer media player recommendations

[low-endz]

Hey Tbers

I really would like a windows media player that has multi equalizer so I can remove some bass to play in with the song and also to remove some of the treble instruments as best as possible to islote the bass.

Speeding/slowing down the track would be useful as well.

I saw another thread that showed free software wich was cool but did not recal seeing anything related to what I am currently adressing.

If any one can direct me to some good playback software options would be cool even if it is directing me to an much older thread.
thanks
