Few pieces of gear define music history as the RS124 does. The custom-built compressors were the secret weapon of Abbey Road engineers during the '60s. The RS124 was an extensive in-house modification of the American Altec 436B compressor. It is believed only 25 units were ever created, and each serial number was hand-built by Abbey Road/EMI technical legends Bill Livy, Len Page and Mike Bachelor.

The Abbey Road RS124 is the Holy Grail of Smooth Compressors. Give your music the sound of silky-smooth Abbey Road RS124 compression – the legendary velvety tones heard on every Beatles recording made at Abbey Road. With two distinct flavours to choose from, this classic tube model is the only software emulation of the ultra-rare RS124s approved by Abbey Road Studios.
