Built from the ground up with the best available components, the MXR GT-OD Overdrive pedal creates smooth, warm, and classic overdrive without excess noise or tone coloring. The simple controls make it easy to dial in a great tone quickly—from crunchy rhythm tone with chord clarity—to sparkly and harmonic-rich lead tones with tons of sustain. You won't find an overdrive that is more organic, responsive or open sounding.
