I stumbled on this video the other day. It’s a great cover of Queen’s Bohemian Rhapsody by jreng. Looks like he shows a video clip of each audio source in the song. This thing must have took FOREVER to put together.. both the audio and the video. That’s a lot of work. In the video, it looks like he pretty much uses Electro-Harmonix pedals for the effected signals.
