BASS
Bass is perhaps one of the most diffi cult instruments to record faithfully, since
by its very nature it’s a bass instrument and as discussed in Chapter 1, bass has
a long waveform. While all frequencies will refl ect off walls, due to the length of
a low-frequency waveform, if you are recording in a small room there will be a
culmination of low-end frequencies at the microphone, even if the microphone
is pointed directly at the amp cabinet. This results in more ambience and colou-
ration being captured by the microphone which can result in a muddy sound.
On top of this, the bass is an absolutely vital element in a dance mix, it is part
of the groove that you dance too, so it has to be recorded perfectly.
The fi rst step to recording a bass instrument is to ensure that the bassist can play
the instrument well and that it’s tuned correctly. A poorly tuned bass instrument
will result in a nightmare at the mixing stage. Also, while fret noise is acceptable on
an acoustic guitar it should be avoided on a bass guitar; while this can sometimes
be avoided by setting the string height from personal experience, the majority of
the cause is a result of an inexperienced thumb-slapping dickhead attempting to
show off his talents rather than concentrate on achieving a good take.
Similar to electric guitars, you can use DI box to record the bass but it is of
paramount importance that you use a good DI unit such as the Ridge Farm Gas
Cooker. However, while this type of DI box will result in a clean focused timbre,
do not underestimate the room ambience that can be captured by capturing
the sound through a microphone. Consequently, it is advisable when record-
ing bass to use both a DI box and a microphone to capture the sound; both
can then be mixed together during the mixing stage to attain the best results.
Recording directly from a bass amp is diffi cult since you should have a fairly
dead room to record in. This is because both refl ections and reverberations
from the room will be captured and, as discussed in earlier chapters, reverb
should be avoided on bass since it will severely affect the position of the bass
when it comes to mix-down. You need to ensure that you record in the biggest
room available to prevent the refl ected waveforms returning to the microphone
and adding more bass end than you wish to capture.
Generally speaking, microphones with a good low-end response should be
used to record the amp cabinet; if pushed to recommend a microphone, the
Sennheiser E602 produces very good results but some engineers will use a micro-
phone designed to record kick drums since they’re designed to capture the lower
end of the frequency range. Again, experimentation is the key and you should
experiment with as many different microphones that you have at your disposal.
The microphone placement is generally the same as electric guitars in that if
the microphone is placed directly facing the centre of the amp cabinet it will
capture more of the higher frequencies, whereas if it is placed further to the
side it will capture more of the lower end of the spectrum. As a starting point,
try placing the microphone approximately 600 mm above the cabinet, pointing
downwards towards the amp and roughly 400 mm away.
