SGA1566 Free Tube Preamp Simulator

SGA1566 Free Tube Preamp Simulator

SGA1566 is a free tube preamp simulator/tube saturation effect plugin by Shattered Glass Audio.

SGA1566 preamplifier is loosely based on a single channel all tube vintage preamplifier. The whole circuit is simulated in real-time using the high-performance circuit simulator. This level of sound fidelity comes at a price of high CPU utilization. For cases where such a CPU hit is prohibitive, Shattered Glass Audio has added a model that is significantly less CPU intensive but slightly less accurate than the circuit simulation.

You can use SGA1566 preamp to add warmth to a track, as a saturation compressor, or to add “dirt” with tube overdrive.


  • Authentic analog sound through real-time high-performance circuit simulation.
  • Two-band active Baxandall EQ that can be placed either before or after the preamp.
  • Up to 4x oversampling.
  • Mono or stereo processing mode.
