For sale of comparison, my '22 SB-2 and '88 L-1000, both in factory tolex cases.
The L-1000 is secure, doesn't move, has the neck supported in multiple areas and has ample padding around the back of the bass.
The SB-2 has an open area, only one neck support, and can move by about an inch in any direction. Plus the storage pocket is half the size and there are no feet for the case when laying flat on the ground.
Here's a closeup of the gaps on the SB-2 case. It doesn't surprise me that tuners get knocked loose when there is this much room for the bass to slide around.
I know that G&L buys the cases from G&G, so I don't totally fault them for it, but they're pretty poor for what amounts to a $2500+ instrument.
