The Logic Off Topic list

I once heard the guy who wrote the music for the Gary Glitter hits in the
early 70's talking about the guitar tone used on those records (eg Rock and
Roll part 1 and 2). He said he had an idea for a recording technique,
tried it in the studio and got that sound more or less straight away.
Unfortunately, he did not elaborate on what the technique was. Anyone know
how that sound was achieved?
