The Pedaltrain Classic Junior pedalboard is a compact, durable and smart solution to all your pedal board needs. Including all necessary pedal mounting hardware in the box it also comes with a padded soft case which makes it super easy to transport to gigs and practice sessions. The cable ties and adhesive strips allow you to get all your pedals and cables really tidy.With 4 rails this board will hold around 10 standard sized effects pedals, more if you have smaller ones and less if you have bigger ones. It's deep enough for a wah or volume pedal. The Voodoo labs or Pedaltrain Volto power supply will mount underneath the board. Mounting hardware is sold separately.These are really cool boards and they make life much easier when putting them together!
