Hi guys, I saw this image on the interwebs - Elvis playing a bass. At first it looked like an old P bass (the fender logo is kinda visible), but on second look it seems to be shorter in scale. I'm not a bass player so I'm really not up with what's-what in bass land, so can anyone help ID what it is?

Its the top image on this site: https://www.elvispresleymusic.com.au...965-march.html

According to the site, the pic was published in a magazine called 'The Commercial Appeal' on March 7, 1965 - so we know the bass is mid 60's or earlier.
