Function f(x) Third Rail Overdrive


The Third Rail is Function f(x)'s first foray into the overdrive realm. Their design objective was to create a versatile overdrive that could deliver a range of compression, saturation and touch sensitivity to excite the sophisticated ears of modern players. They quickly figured out that while ther design sounded great on its own, putting two of the circuits in one box took it over the top.

The Third Rail features two independent discrete overdrives utilizing NPN transistors. Each channel is identical and includes a diode clipping switch and one unique switching option. The Clip switch lets you choose between Schottky, no diodes, or silicon diode clipping for different levels of compression, touch sensitivity and headroom. The left channel has a high Gain switch and the right channel has a Bass cut. All of the options will let you tailor the Third Rail precisely to your rig.

Each channel can be run independent from one another or in series. Choose a single channel for rhythm playing or low gain leads. Slam both channels into action for high gain saturation and compression. They also give you three bypass modes to choose from: one on at a time, toggle between each channel, or switch both channels on at once (with momentary bypass on the second footswitch for stutter effects). Best of all, the Third Rail remembers which mode you prefer even if you unplug the power supply!
