The RockBoard pedalboard series is based on the innovations of our completely re-designed pedalboard series and incorporates a lot of added features, based on suggestions from musicians all around the world. The ingenious, lightweight, rigid and rugged construction, based on only one sheet of cold-rolled aluminum and U-shaped vertical support braces for additional stability, as well as the innovative slot-based design lets you hide cables easily for a neat and tidy design, all stay the same. Added and improved features include an extended slot grid for perfect fit of our new optional QuickMount plates, added mounting positions for the Optional RockBoard The Tray - Universal Power Supply Mounting Solution (QUAD 4.2, CINQUE 5.2, 5.3 and 5.4), second MOD mounting slots for RockBoard CINQUE 5.3 and 5.4, lighter ABS pedalboard cases and improve pedalboard bags.
