The Silverfox is a low-gain overdrive pedal with a unique circuit design. It features several controls that allow for versatile tone shaping. The VOL control adjusts the output level of the effect. The GAIN control determines the amount of overdrive, with higher settings producing more distortion. The TONE control is similar to a Muff style tone control but has a distinct voicing. The BASS control, which is a trimmer in the stock unit, increases the low-end after the clipping stage. The MID control, a fixed resistor in the stock unit, can cut or focus the mid frequencies. The PRES control, also a trimmer in the stock unit, has a limited range and adds a subtle amount of clipping to the low to upper mids when turned up, but only when the MID control is set high. Overall, the effect of the PRES control is minimal. The Silverfox offers an elegant approach to overdrive with its unique circuit elements and versatile controls.
