Pedaltrain PT 2 / HC is a great deal at $200. The hard case has wheels!!!!!
There is room across the top and down the right or left side of the pedalboard (depending on which side you mount the HD500) to mount smaller type pedals...
FYI: There is a small amount of room to mount an expression pedal on the PT board but its too close to the HD500 volume pedal
(IMHO) so I remote the expression pedal to the right of the PT pedalboard. The PT hard case has a storage area that holds lots of goodies too... expression pedal, Fishman Aura, picks, instrument cables, G50 wireless antenna whips, spare strings, and a small bag of guitar tools. The PT 2/HC also includes velcro, zip ties, and mounting hardware for Voodoo power supplies (make sure its all there before you buy)
Pedaltrain pedalboard cases have held up very well with the airports too!
Best,
Bryan
