This high-gain distortion pedal was originally released by DOD as the FX69 before being transitioned to the DigiTech brand. Designed by Jason Lamb, it was famously used by Kurt Cobain as a satirical addition to his pedalboard, though its aggressive circuit became a staple for 90s alternative rock and metal. The controls are uniquely labeled "Loud" (level), "Low" (butt), "High" (face), and "Grunge" (gain) to reflect the aesthetic of the era. It features a dual-output design, providing a standard amplifier output alongside a dedicated mixer output with cabinet emulation. The pedal is known for its extreme gain range, which remains saturated even at its lowest settings.
