The Abbey Road EQ that Guides You to Musical Decisions. Even the most modern productions revere the classic sounds of the 50s and 60s—like those from the RS56, the very first parametric EQ. A silky smooth, powerful and musical stereo EQ, RS56 is perfect for loops, drums and synths, or the entire mix bus. Created in the early 50s for mastering, the RS56 was used extensively in the vinyl cutting rooms. But before long, Abbey Road’s recording engineers realized it was superior to the basic tone controls found in that era’s consoles—and it quickly became a go-to option, famously heard on the Beatles’ recordings.
