In extreme instances, and I've survived the process though it's a painful one, the
old "hold the finger against the tape head" technique still works. A couple of years
ago I was sent an aircheck of the first Stan Freberg Show..the "as aired" version,
not the one he put out on Capitol and on CD. Nothing would facilitate complete head
contact except my index finger. For half an hour. (Okay, if you get tired let's
assume you can stop and start and edit.)
