The smooth Gain control helps you dial in the sound you want. If the output level is too high, you can ride the level down with the separate Level control. Pressing the "High" switch increases the gain in the first opamp pair, increasing the maximum gain setting to +75db. With different Gain, Fader, and High button settings the Pants can produce many different tones with the same amount of output level. The front panel DI goes through a FET buffer into the input transformer, adding an extra dimension to the sound of the preamp. Two LEDs clearly indicate signal level for the gain and output stages at a glance, turning green to indicate signal present, yellow for 10dB below clipping, and red for clipping. For easy serviceability and tweaking, the Purple discrete opamps can be replaced with any standard discrete opamp or a DIP-8 IC. The Pants uses our custom output transformer which provides two isolated outputs (when supported by the chassis).
