The Classic 2 should be familiar to you.Based on the original PT-2, the Classic 2 features Pedaltrains original four-rail design and traditional rail spacing.However, the Classic 2 has been updated with an open front design (portholes are history) making power supply mounting more flexible and convenient. The elevation has been raised by approximately 1 inch to clear a wider variety of power supplies and switching systems. Classic 2 is available for purchase with either Pedaltrains fitted soft case (featuring a heavy-duty metal zipper and reinforced stress points) or Pedaltrainsprofessional-grade tour case.
