Does the Zakk Wylde Overdive have more bite than the Sd-1 becuase i hear Zakk Wylde uses the SD-1.

I've personally tried both and the Zakk Wylde sucked balls. It just added more noise.

The SD-1 is a much better choice.

And no, Zakk uses his own pedal (I've seen his pedalboard from his previous tours)

The Zakk Wylde, oddly enough, is a modified SD-1 circuit, which has a little more output, and is 'tecnically' better (meaning, in theory it should be alot better)
