i've had both in recent years, i thought "yeh i'll get a hardcase for my new purchase i'll use it all the time" did i heck as like!! too heavy not enough room for carrying other items such pedals, cables etc plus it would'nt go in the boot of my car out of sight of the scummers. So i bought a ritter gigbag which basically did all that the hardcase did'nt!
Anyway i have a Warwick gigbag now which is more padded than the Ritter to keep my SUB as snug as a bug in a rug!
I'd only buy a hardcase if i had a bigger car and was gigging alot.
