Hello everyone!
I know this post is kinda old, but I have some knowledge about this topic. The readership has postulated as to whether or not a Gibson RD Artist Bass would fit into a Gibson Thunderbird case by Gator or other. The answer is definetly "no". The RD "wing" is wider by 1/2" than the case. The Thunderbird is more Rhomboid shaped. (Diamond) It tends to drop lower than the RD's shape. I bought a Gator Thunderbird case off Amazon. The price is nice at $185.00. I loved it! But the RD headstock won't fit either. I was disappointed. There's just no way to get the RD Bass into a Thunderbird case. Sadly, I sent the case back to Amazon. Your best bet - call Gator Cases in Tampa, Florida. The website doesn't do it for me. You could try to use their "case finder". But It doesn't allow you to select Gibson. It's not up to snuff. If you call them, and enquire about a case for an RD Artist Bass by Gibson, you may get better results. I, myself am contemplating taking action on this very topic. I hope this helps anyone who is searching for a case for a Gibson RD Bass - (Artist, Custom or Standard). TKl cases #8836 will fit however it costs $300.00 online.
