It fits fine . A bit of space around the neck but I'm always super careful with my basses . If you want a bit of extra protection , go for the FB1225 .
Off the top of my head , I would say don't worry about an earth connection at this stage and address the problem if it arises . I will give it some thought and get back to you . Is this another 3D printing exercise Rob ?
As recommended above . The only case I found that would fit my Burns Bison . Same length as the Bongo . You will have to remove the additional cushion at the bottom which is attached by velcro . Not tried it but the Fender FB1225 was the only other one that may have fitted . The Gator is a fantastic case .
I would seriously check out a Sterling in person . The one I bought brand new was one of the shocking QC fails with a busted truss rod and tuners made of toffee . It was returned to the seller in person . Never again for me .
Bought one of these to use for background music at Xmas street party between sets . Battery lasts 8 hours . Music straight from phone playlist . Straight into spare channel on PA .
Over on the other forum there is a thread that runs to 39 pages over the last two years plus . Many reports of problems . I did get a duff one and I will never buy another . I don't know if I can post a link to 'the other side ' here but if you search for Sterling ray34 sparkle basses over there you will find what I mean .
