MXR GT-ODVerified

From the post

Some of you may be thinking this layout looks pretty familiar, and yes, it is extremely close to the ZW-44 Zakk Wylde overdrive. So close in fact that I've included a switch that will select either the GT-OD or ZW-44 on the fly. I've got an original ZW-44 and really like it, but watching some of the clips I think I like the sound of the GT-OD more so I'll certainly be adding this to the collection.

Info from MXR about their original:

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.
