Brian May On The Creative Use Of Delay...

One of my earliest influences on guitar was Brian May, of Queen.  His playing was always different from the standard pentatonic runs of most of my other guitar heroes.  I was always intrigued by his melodic runs and use of amazing harmonies. 

Today I came across this video in which he shows us how he uses a delay pedal (sometimes more than one delay pedal) to achieve some great sounding harmonic runs with just one guitar.   Very inspiring.
