Lightning Boy Audio OP-2 Comp - Vacuum Tube Optical Compressor


Lightning Boy Audio

Superior in every way to the highly acclaimed LBA Opti-Mu Prime compressor pedal.  5% more output gain, 60% less noise, wider range of compression, more obvious sounding compression slopes (knee), Lower THD (cleaner tone), widely extended frequency response.  Worthy of a new name.  Lightning Boy Audio is excited to introduce, Op-2 Comp. Designed for the studio, tough enough for the road.  


  • Vacuum tube powered optical compressor.  Uses the exact same photo resistor as the famous studio compressor, the LA-2A, for that the same, much loved, auto-release characteristic.  
  • Super transparent compression capable of being gentle and mild or highly controlled squish.
  • Clean tone with a touch of vacuum tube warmth.
  • Ultra low noise, even with the volume and compression at full.     
  • Ships with a select pair of new-old-stock 12AU7 vacuum tubes installed
