Your new favorite booster.

  • Single stage ultra high gain JFET booster/preamp offering kind-of clean amplification to overdrive and warm distortion to murder-your-face amplification.

  • Two amplifier topologies available via PCB mounted switch. "Half Stack" and "Full Stack"; the latter injects a pair of matched current sources creating an additional +40dB of gain with softer clipping.

  • Two modes of negative DC feedback for each topology via PCB switch; 'linear' and 'nonlinear' offering slightly different gain and frequency response characteristics.

  • Shipping included for all 50 United States, Guam and US Virgin Islands.

  • Flat $35 shipping charge for international orders.
