... Windy & Carl, Stars of the Lid: all these guys have a distinct, unique sound because of the guitars; with synths, it just wouldn't be the same.
yes ... a lot of threads about that on hypnos forum was lost, showing my point of view about my motivation of use of guitar as sound source (infortunately all old releases of this forums post database seem lost ... that's a big pity).
Robert Fripp, Robert Rich, Jeff Pearce, Adam Wiltzie (Stars of The Lid), Carl Hultgren (Windy&Carl),
are all artists that used (use...) (guitar) string vibration as "source" of further elaborations .
I think that electro-acoustic ("analogic") waves possess huge complexity/richness that personally I never obtained with (digital) synths. This come in evidence when the strings are plucked with e-bow (just yesterday I relistend "Stars of the Lif "ballasted orchestra" that is played 90% with e-bowed lap steel guitar); the e-bow super-excitation of string produce chaotic waves, that made the sound so rich ...
The electric guitar as the primary source for creating ambient music seems a tad overlooked.
I agree with Alan that it can be the processing that makes the sounds interesting, but not
necessarily just a bit of scratchy, glitchy jiggery-pokery kind of thing. The software available now
can really transform the source sound - naturally, it helps if people play something interesting in
the first place ! All manner of looping, granular synthesis, spectral manipulations and the like
allow for a lot of scope.
I was pretty much introduced to ambient by Eno's music, so I initially thought it was all treated
synths and Rhodes Piano, but I discovered lots more.
yes... personally I dislike the computer-elaboration of guitar source with computer filters (just that "re-sampling" as you define "scratchy, glitchy jiggery-pokery kind of thing") that I "indentify" with Fennsz music (I'm sorry) and a long sequel of guitarists that does the same ...
btw, Rhodes piano (an instrument I really love) is another good example of beatiful "analogic" source vibrations ... in that sense it's a n input similar as a guitar: because the electro-acoustic/mechanical source generation ... every note is really unique and sound processing of rhodes chords achieve amazing results ...
