Is that Cortez somewhat new, or extremely old? The reason I ask - I owned a 1977 Cortez Jazz bass copy, purchased new. It was my very first bass. I would be surprised to learn they are still making basses.Funny you should ask - I own 2 basses and one of them is a P bass
The other is a Cortez copy of a Gibson Ripper.

a Mustang?!?
