Chris, you really should have gone deeper into the history of delay, when they built long rooms with speakers and mics they could move to different positions, closer or further from the source. to alter the delay time, and multiple mics for additional repeats...hence the term 'echo chamber'.  Then some brilliant person decided they could loop tape through multiple heads...the rest you covered well.  Definitely Les Paul was one of the pioneers in this..but there are others as well...

Also Strymon just put out some similar articles recently...http://www.strymon.net/2014/09/15/pete-celi-premier-guitar-history-doubletracking/

One word for the n0oBz...earplugs...wear ear plugs...sorry...WEAR EAR PLUGS...you will thank me later...

Strangely, jefe, this is a topic under discussion over in Solos & Duos.
