Fulltone delivers the Full-Drive 3 guitar pedal overdrive and boost effect. Unlike its cousin the FD2, the FD3 uses both a JFET input and a JFET op-amp. Along with great sound, these JFET’s give the FD3 an ultra-high Input impedance which allows the pedal to mate with any type of pickup and react well to changes in your guitar’s volume control. The switch offers 90’s, WIDE ASYM, and COMP-CUT modes. Full-Drive 3 also allows you to choose between Overdrive and Boost channel. Volume, Tone, Overdrive and Boost can be easily controlled with potentiometers.
