I found this pretty interesting video from over a year ago. This video has Chris Carter creating ambient sounds using a bucket of Boss pedals and a BC, Gakken and BugBrand synths. No guitars in the mix, just synth signal.
Here is what Chris said about the video:
This is a brief tribute I made to the experimental work of the BBC Radiophonic Workshop who recently staged a performance in London, that I couldn’t attend. All the sounds and loops originate from the BC8 synth, the Gakken SX-150 synth and the BugBrand Weevil synths. All the effects and processing is done with the Boss pedals. Oh yeah… and I did the whole thing ‘upside down’.
