I totally stole this idea off Mervin John, guitarist and band leader extraordinaire, when he brought his rig down for us to check out during our band arrangement class. If you have a heavy pedalboard, need a luggage-chucking grade case which has wheels and can be locked during transit, you can most certainly use:
I suppose I'll lose some baggage allowance and won't be able to buy back snacks for anybody when I'm away on tour, but it's a necessary sacrifice on the war on tone. There's no need to fork out $200 on a ATA flight case with wheels, save for the fact that it's probably the more elegant and pro looking way of transportation than this!
