First download alsaequal:

<code># tazpkg get-install alsaequal</code>

Then create a /home/tux/.asoundrc file:

<file>
ctl.equal {
  type equal;
}

pcm.plugequal {
  type equal;
  # Modify the line below if you don't
  # want to use sound card 0.
  # slave.pcm "plughw:0,0";
  # or if you want to use with multiple applications output to dmix
  slave.pcm "plug:dmix"
}

pcm.equal {
  # Or if you want the equalizer to be your
  # default soundcard uncomment the following
  # line and comment the above line.
# pcm.!default {
  type plug;
  slave.pcm plugequal;
}
</file>

##	mixer_device	"default"	# optional
##	mixer_control	"PCM"		# optional
##	mixer_index	"0"		# optional
}
</file>

And start/restart mpd and you should be able to use //$ alsamixer -D equal//
