The Pedaltrain Powertrain 1250 is a quiet, primarily 9-volt supply with innovative features. Designed in cooperation with the engineers at Nashville's Creation Audio Labs, the Powertrain 1250 gives you selectable voltage (115v or 230v) operation, letting you use your Powertrain 1250 anywhere in the world with confidence. Seven 9V outputs, plus one variable-voltage output, give you major flexibility in setting up your pedals. Simply drill four small holes using the supplied mounting template, and the Powertrain 1250 mounts neatly, without mounting brackets, underneath your Pedaltrain (excluding NANO and MINI). Power your Pedaltrain right, with the Powertrain 1250.
