The Aria Compressor Drive combines Keeley’s Red Dirt Overdrive and Compressor Plus effects in one stompbox, offering Keeley Engineering’s most flexible overdrive to date with all the tone and blend features of the Compressor Plus. Players also have the ability to swap the order of the compressor and drive for two very useful drive experiences. The Aria Compressor Drive comes with TRS insert jacks to allow you to divide the pedal into two units. Insert effects between the two sides! Compressor into delay into overdrive, anyone? Maybe swap that for overdrive into delay into compression.
