I have a 1994 Rickenbacker 650 Dakota that I recently bought used. The case that came with it, black exterior/blue interior, is a little too big for it. It almost looks like a case for a 330.

I contacted Rickenbacker and they told me to order a 600/350 series case for new one. I just got it today and it does not appear that my 650 fits. The neck doesn't even make contact with the neck support when you lay it in the case and it appears the headstock extends past the space designed for the headstock.

I haven't tried to close it because it really looks like I'd have to "force" it closed. It does not look right to me at all.

Did Rickenbacker change the body size/style of 650's at some point such that a 1994 model would not fit a contemporary case?

Sigh...I think I may need to send this one back, but now I don't know what to do about having a case that fits.

Measure the inside length and width. Post a photo of the case with the guitar.

I will measure my 650 case. Maybe they sent you the wrong case. Who did you order it from?
