In 1986, I designed one of the first modifications of the Neve 1272 line amp
into a microphone preamp. The idea was then taken up by Brent Averill.
I had an opportunity, in 1991, to work on REDD 37 which was one of two
custom made consoles the Beatles used to record their classic songs at the Abbey
Road EMI Studios. This console contained the famous Telefunken/Siemans V-72s
module. I later designed one of the first modifications of this unit to
a microphone preamp with direct instrument input.
