Here's a sample of the Boss XS-1 used for obtaining an effect somewhat similar to that of an 8 string octave course bass, using my 28.6" scale Ibanez GSRM25 Mikto Bass, tuned to E standard tuning (E to C).

Just random noodling through my "amp-less" setup, directly into my Zoom H4n handheld recorder, with nothing additionally done post recording, other than clipping/cutting some parts out.

Boss XS-1 8 String Octave Course Bass Emulation

Sweet, sweet noises... 

Experimental dark drone/ambient - Alternative folk - Psychedelic electronic

-

This is where almost all my music related output ends, from solo projects, sound tests of gear, to just stuff made for the sake of the experiment or fun of it....

Enjoy!
