Right now I've got my Ibanez SRC6 in a shitty bass gigbag, but I'd like to get something better so I can actually bring it to jams.
What's good? I know it's a bit of an outlier instrument.
I just haul mine around in my Dingwall gigbag.
They're all different sizes, shapes, and have the bridge on different points in the body, so you'll have to either take close measurements and find companies that provide detailed case measurements, or try out a bunch to see what fits.
Mono has detailed measurements for all its gigbags, including body length and overall instrument length, and they're super protective (albeit quite expensive). Might be worth checking their Vertigo and M80 range out in both guitar and bass to see what fits.
