Re: ELP and directional bass Re: Re: surround looping


Bass is not just bass.  There are plenty of localize-able overtones 
produced in a good bass.

The low E on a bass (E1) is a bit more than 41Hz (and has a wavelength 
27 feet long) which can not be localized very well.

There are at least ten harmonics you can hear however, which brings it 
up to 410 Hz - which is high enough to localize on (2.7 feet).  A 
conventionally tuned four string bass G string at the 12th fret (G3) 
has a fundamental of 196Hz (and a wavelength of 5.7 feet) - the tenth 
harmonic of this is 1960 Hz with a wavelength of a bit less than 7".

This is extremely easy to localize.

Also when Greg Lake plays through a fuzz box (or breaks up his amp) - 
guess what - lots more harmonics - that is what fuzz is - gobs of 
harmonic (and also not so harmonic) distortion.  The net result is - it 
is even more easy to localize.

So you are quite right in thinking this is quite directional to you.
