I've done searches but can't find specific mentions of what pedals Weiss used into his GK/Hartke setup. End Of Silence is to this day the benchmark of distorted, auto wah bass I've heard. I saw an old live video where it looked like he had two Boss? pedals taped together near the foot of his cabs. One looked like the color of an ODB-3 and the other I believe was white. Anyone know for sure?
