Redd.47 Notes:

The "Beatle Preamp"

Source: Revolution Recording Equipment - California, USA.

Reproduction of the original REDD.47 mic preamp that was utilized at Abbey Road EMI Studios during the mid to late 60's.

"...The REDD.47 was a wonderful sounding amplifier and was by far the most-used mic amp on Beatles sessions, being called upon for essentially every Beatles track recorded after 1963. It was certainly responsible for some of the unique character of the 1964-1968 Beatles recordings, particularly in the edgy treble regions."
