 Kim - thanks for that confirmation.  I had 
seen on the web, Mike Battle's name, and dates ranging from 1960-1963 for the 
"creation of the Echoplex". 
  
Richard - you are an amazingly rich and generous 
resource! :)  Thank you for calling the man himself. 
  
So, then... if Mike Battle starting making 
prototype 'Plexes in the late 50's, was he aware of, or involved in, the 
activities of Riley, Oliveros, Reich, et. al. at that time?  Was it really, 
as it seems, that an Echoplex made it into Riley's hands... he explained it to 
someone... who implemented the idea in a different way (large tape decks)... 
which Riley tagged the "time lag accumulator"... which Riley continued to use 
and others used later as live looping devices... sorta like that? 
  
Again, curious. 
  
Thanks!

  I would guess production would have started 
    sometime later, so the dates don't appear to match up quite 
right. 
  
  
  I just called Mike Battle, and while I can't say there's a definitive 
  answer to this question, here's what he told me: 
  
  
  Mike and a friend started building tape delay units in the late 1950s, 
  and the units would dribble out to various musicians. It wasn't until 1964 
  that he received a patent for the Echoplex, but it seems likely that a number 
  of them were in circulation under that name even before that date. 
  
  
  I've found references with dates of 1960 and 1962 for the Echoplex. 
  
  
  Analog Echoplex fanciers will be happy to know that Mike Battle's new 
  design, the "TubePlex" will be available in numbers at the summer NAMM show in 
  Nashville 
  
  
  
  
  
  
  Here's what Ramon Sender told me about his early exposure to and use of 
  tape systems: 
  
  
  If Pauline is referring to feeding one tape through two 
    Wollensaks, 
  the first on record and the second on playback, this set-up was 
    first 
  demonstrated to me by Terry Riley who I think said that he 
  and 
  Lamont Young used it during a dance performance of Anna 
    Halperin's 
  troupe during the period they were the composers involved with 
    her. 
  I then used it for a 'piano canon' performance during a Sonics 
    Concert, 
  if I recall correctly. We're talking the fall-spring of 
  1961-62? 
  
  
  I also had an Echoplex-type machine at the Conservatory that 
  I 
  abused happily during some early tape pieces, until I 
  discovered 
  I could get a more natural echo by recording in the men's 
    bathroom. 
  
  
  
  
  Les Paul's thing was the Les 
  Paulverizer. 
  
  
  ...which had nothing to do with tape loops. It was just a button mounted 
  on his guitar that enabled him to start and stop a cassette deck with a 
  prerecorded backing tape on it. --
