Frequently asked questions

INPUT DRIVE controls the preamp gain, similar to the Drive, Volume, or Gain knob on a physical amplifier. Its frequency response varies with the knob position due to a bright cap.

INPUT TRIM is a clean, linear gain applied at the input to adjust the relative gain of the preamp, analogous to changing the V1 tube in an actual amp.

DAMPING controls the amount of negative feedback in the power amp, affecting output impedance and speaker interaction. Higher values yield a brighter, tighter sound, while lower values provide a smoother, grittier tone.

XFORMER MATCH changes the turns ratio of the output transformer, controlling how easily power tubes are driven into clipping. Decreasing it delays clipping, while increasing it compresses the sound.
