**Nonsense. The lowest useful frequency from a bass
guitar is higher than 80Hz. Almost no fundamental is
audible. It's all second harmonic.

Written by someone who has obviously never actually
analyzed the signal that comes out of a pickup from a
bass guitar.

**Wrong, but I have certainly not examined all of them.
In fact, I've only examined 3 or 4. All were 4 string
bass.

The fundamentals can be there if you don't lose them
along the way.

**Sure. The fundamental is at such a low level, that few
ever hear much of it.

I just pulled up the bass track from a multitrack recording that I made at
church. The most intense harmonic was second, followed by fourth, third,
and fundamental. The fundamental was only 8 dB below the most intense
harmonic, the second.

**Which is not too far from my own measurements.


I do suspect that few bass guitar amps are actually
competent reproducers of the region 32 Hz, which is
approximately the fundamental of the lowest note
playable on a 5-string bass guitar.

**The AMP may well be a competent reproducer of the
lowest frequencies, but the speakers rarely are.

Agreed in that I was speaking of "guitar amp", the common nomenclature for
an assembly that includes the speaker.

FWIW, most players filter out the lowest frequencies anyway.

Not the case with the players I record. We boost the bass end of this
channel pretty hard, with a pretty steep roll-off. I don't have the
mixer at hand, so I don't know the exact frequencies, Qs, and boost. If
memory serves, there's a 10 dB peak in the 40 Hz range, Q on the order
2, plus other filters. Everthing above 2 Khz is filtered out very heavily,
but there's a big, more gentle roll-off starting around 150 Hz.

They tend to prefer a 'faster' more 'articulate' bass.
This means that frequencies as high 1kHz are often
boosted.

That gives you a sort of slappy, twangy sound. Different horses for
different courses.

**Of course.
