PAiA TubeHead

Projects > PAiA TubeHead

The TubeHead is a two-channel tube gain stage which can be used as a hi-fi preamp or a tube saturation effect. By feeding very low plate voltages to two 12AX7s, the TubeHead maximizes the compression and distortion characteristics of the tubes. “Drive” and “Blend” controls allow the user to adjust the amount of tube saturation imparted on the signal.

  • Uses Sovtek 12AX7 tubes
  • Starved plate design
  • “Drive” and “Blend” controls
  • Optimized for unbalanced, line-level inputs
