OVERVIEW

The Chandler Limited REDD.47 Preamp is a meticulous recreation of the legendary EMI REDD.47 line amplifier, which was originally designed for the iconic REDD.51 recording console at Abbey Road Studios. Used in countless classic recordings between 1964 and 1968, including The Beatles’ tracks, the REDD.47’s unique punchy, aggressive character became a hallmark of Abbey Road’s sound. The Chandler version has been enhanced for modern studio needs, offering greater gain and tonal flexibility while preserving the vintage character that made it famous.
