Tighten up your bass with a low pass filter

#AudiotentTip 276. Low Pass Bass.

Most of the time we use a high pass filter on a bass to get rid of any unnecessary rumble in the lowest frequencies (usually below 20-40hz). This makes some extra headroom for your track and tightens up the bass nicely.
However, there is another technique you could use on a bass to make room for other instruments in your music. Simply add a low pass filter and get rid of any unnecessary top end. It will make your bass warmer and create space for brighter instruments.
