MASTER: The classic loudener knob; you know what this does.

PRE-AMP: The Little Secret consists of two mu-amp gain stages while this control governs how much of the first stage is let into the second. This translates to gain, slight compression and tube-like growl.
The Little Secret accepts a standard center-negative 9-18V DC power supply. The current draw is extremely low, any power supply that fits the above specifications will perform admirably. Don’t use any other type of power supply (AC, higher voltage, center-positive) or you run the risk of ruining your new pedal and quite possibly rendering it useless. There’s nothing clean about that! Check your supply!
