I use convOut=-af equalizer=f=3520:width_type=o:width=4:g=4 to give the trebble a boost. This works fine.
To apply the change hit the apply button and restart MinimServer.

The reference frequentie f is the middel of the bandwidth that is boosted.
Width_type o means the bandwidth is set in octaves.
(for octave frequenties 55, 110, 220Hz etc., see Wikipdia)

Changing the boost value g (gain) between -4 and 4 the difference is easy to hear.
Be careful not to blow your speakers with higher gain values!

You can set the bandwidth in Hz too (width_type h), however the maximum bandwith is 999Hz. In the higher frequenties (5kHz) this bandwith is to small to hear a difference.

I also tried convOut=-af equalizer=f=58:width_type=h:width=4:g=-8 to suppress the bass. This needs more experimenting on.
