Thanks for all the responses folks. First off, I love the bass - totally playable, powerful sound, and a familiar feel as my previous bass was an Ibanez GSR200 with typical Ibanez narrow neck. I tried the Fender Precision and although I liked the sound I couldn't get the hang of the neck profile at all.
The bass is definitely the new Pro model, the case looks like the new model, so as far as the Pass Cert is concerned, I'll stick it back in the case and get on with playing
Cheers, BrB.
