The Jackson Audio Hour Glass is a groundbreaking dual analog compressor pedal inspired by the legendary Ross compressor. Featuring two fully independent OTA-based circuits, the Hour Glass offers unparalleled tonal control, extended sustain, and transparent compression for guitarists. With selectable Fast, Medium, or Slow attack times and a three-way Treble boost switch for each channel, you can tailor the pedal’s response and high-frequency character to any playing style or guitar. Use one compressor for single coils, the other for humbuckers, or engage both simultaneously for endless sustain. Precision controls for Level, Sustain, and Blend on each circuit let you dial in everything from subtle, natural compression to bold, expressive squish. Built for reliability and creative freedom, the Hour Glass is the ultimate compressor for stage and studio.
