The Metro Series is Pedaltrain s first three-rail pedal board system. Pedaltrain s Metro Series is perfect for players who need a portable, grab-and- go solution. Musicians who live or work in urban settings or tight spaces will appreciate Metro s low profile, horizontal orientation. Metro 20 is big enough for your essentials, including most multi effects units. Metro 20 is available for purchase with either Pedaltrain s fitted soft case (featuring a heavy-duty metal zipper and reinforced stress points) or Pedaltrain's tour grade case.
