As you know the series 1 case is very heavy and unbalanced to carry, although it protects the bass well. I do want to get a solid/sturdy gig bag that fits the length of this bass (49in x 14 in x 21/2). Big bass needs a big case. The ROADRUNNER HIGHWAY PREMIUM case is well built, but the series 1 does not fit! The MONO case is too small as well. Perhaps, there is a custom shop that can build the case--Very expensive. I do want one because i can carry it like a backpack and walk for miles. Sure i can, in the Army(early 20s) i used to carry the Radio, batteries etc....that was at least 80lbs on my back! LOL.
