Any other kinds of bags or cases are inappropriate for gigs.

Unless, of course it is called a "gig bag" - gig being the key word.
And if it is a "recording" gig make sure you use a recording bass. A marching gig reguires a marching tuba, unless only Sousa marches are being played, in which case you must have a Sousaphone. Of course if ther is a drought on you will get a BIG pay bonus for bringing a raincatcher.
REMEMBER It is using the Right equipment that counts!!!!!
WHAT!!!!!!! Do you mean to tells us you didn't use something with a world class sound, ie one with German Engineering, American Heritage and made in a poor country as a meand of lifting their economy????
SHAME ON YOU Go sit in a corner of the cornfield to purge your sins.
